fix: an address holding only unpriced tokens is no longer totalled at $0.00 (closes #261)

Prices are fetched for the top 25 tokens only, so an address can hold real
assets this build has no price for. The address total summed the priced
holdings and printed the result as the total, so an address holding nothing
but unpriced ERC-20s was reported as worth $0.00 — wrong in the direction
that matters, and on the address-removal confirmation it sat directly under
"This address holds a balance."

getAddressValue() returns { usd, partial }: the value of the priced holdings,
and whether an unpriced holding was left out of it. Worth zero and worth an
unknown amount stay separate facts, as an absent holders_count stays separate
from a count of zero. formatAddressTotal() is the one rendering of that pair,
so no screen can word it differently:

  - nothing knowable (testnet, before the first fetch): no total line
  - everything priced:  "Total: $5,500.00"
  - part priced:        "Total: $3,000.00 plus unpriced tokens"
  - nothing priced:     "Total: unpriced tokens only"

A partial total is kept rather than suppressed: the figure is the ETH and
priced tokens the user does hold and is correct as far as it goes, so it is
named as a floor instead of being thrown away. What is never printed is a
figure covering no holdings at all.

All four call sites read it — the Home summary line, the Home wallet list,
AddressDetail and the removal confirmation — and getWalletValue() and
getTotalValue() carry partial up so a future consumer cannot lose it.
The per-token balance lines are unchanged: a token with no price shows its
quantity and a blank USD column.

tests/addressValue.test.js covers the only-unpriced, genuinely-zero and
fully-priced cases at the helper, at its formatter, and through both call
sites that return their markup as a string. Written first and watched fail
on the unfixed helper: the Home wallet list gave "$0.00" and the removal
confirmation "Total: $0.00" for an address holding 5000 unpriced tokens.

 # Completed Steps
 
-- 2026-08-17: The Settings screen is driven in a browser, and every element id
-  the popup looks up is checked statically. Nothing exercised Settings in the
-  e2e suite, and jest runs with no DOM, so the densest run of `$("...")` lookups
-  in the codebase was unverified at runtime. Seven new cases in
-  `tests/e2e/run.js` reach Settings, assert the About well and the wallet list
-  were actually written, assert the four Token Spam Protection checkboxes are
-  real checkboxes defaulted on, and assert the theme and network selectors offer
-  the choices `src/shared/networks.js` and `index.html` define. The selectors
-  are then driven to `dark` and `sepolia` — neither is the first `<option>`, so
-  neither can be read back from the markup with no JavaScript involved — and
-  reasserted after a popup reopen before being restored the same way, and one
-  spam filter is toggled off and back on across a reopen each way. Those round
-  trips run the change handler, `saveState()`, `loadState()` and the
-  `init()`/`show()` assignments rather than just looking at the screen. `show()`
-  no longer guards its `settings-network` lookup with `if (networkSelect)`: a
-  missing element must fail loudly, which is the whole failure mode this unit
-  exists to catch. Each group records a coverage key and a final case demands
-  the exact set, so a shortened or skipped section reddens the run instead of
-  shrinking it. `tests/popupElementIds.test.js` is the general half and runs in
-  `make check` with no browser: every literal id reached through `$()`,
-  `document.getElementById()`, `showError()`/`hideError()` and `showView()` must
-  exist in `src/popup/index.html`, which no id in `index.html` may define twice.
-  Demonstrated on four deliberate breaks — a typo'd id (both halves red), a
-  handler bound to the wrong but existing element (only the functional e2e case
-  red), a typo in a view no browser suite opens (only the static guard red), and
-  the deletion of both persisted-value assignments in `settings.js` (only the
-  selector round-trip case red)
-  ([#229](https://git.eeqj.de/sneak/AutistMask/issues/229)).
-- 2026-08-17: The phishing blocklist is vendored at build time and censored, and
-  the runtime fetch is gone
-  ([#219](https://git.eeqj.de/sneak/AutistMask/issues/219)).
-  `script/vendor-blocklist` fetches upstream at a pinned commit, verifies the
-  sha256 of the bytes it was served, and writes
-  `src/shared/phishingBlocklist.json` as truncated sha256 digests rather than
-  domain names — which is what removes the competitor's name from a list that
-  carried it 6,475 times, without dropping a single one of those domains.
-  `script/check-censored` runs in `make check` and again against `dist/` at the
-  end of every build, each permitted occurrence scoped to the one path allowed
-  to carry it; the name now appears only in the vendoring script, which defines
-  it once, in the provider-shim identifiers in `src/content/inpage.js`, and in
-  one ERC-20's on-chain name in `src/shared/tokenList.js`. Removing the fetch
-  retired the delta, the persistence and the 24-hour alarm from
-  [#158](https://git.eeqj.de/sneak/AutistMask/issues/158), and retired alarms
-  are now cleared rather than left running on existing installs. Two
-  consequences, both deliberate: the list no longer self-updates, so it is as
-  fresh as the last vendoring run that was released; and re-vendoring from
-  current upstream took it from 231,357 stale entries to 105,721 current ones,
-  because upstream prunes and the vendored snapshot never did. `dist/` fell from
-  18.9 MB to 8.9 MB. The e2e suite now drives the warning end to end from a real
-  blocklisted origin, and its service-worker interception canary has a new
-  anchor, because the startup fetch it used to watch for no longer exists.
-- 2026-08-17: One wording for an empty password field on every screen that asks
-  for one. The private key export screen said "Password is required." where the
-  other five say "Please enter your password.", the same one-condition-two-
-  wordings split that [#172](https://git.eeqj.de/sneak/AutistMask/issues/172)
-  closed for a rejected password. Strings only, no behaviour change.
-  `tests/passwordMessages.test.js` now pins the empty-field guard per call site
-  as well as the decrypt handler, anchored on the `decryptWithPassword` sites so
-  the wallet-creation screen — where an empty field means a password being
-  chosen, a different condition — stays out of the set. Every error container
-  measured at a 360px viewport in the pinned Playwright container: the export
-  screen's container holds at 20px with the following section at the same offset
-  for the old string, the new string and the empty reserved state
-  ([#265](https://git.eeqj.de/sneak/AutistMask/issues/265)).
-- 2026-08-17: One shared extension-API module,
-  [`src/shared/browserApi.js`](src/shared/browserApi.js), is the only place in
-  the tree that names `browser` or `chrome`. Every call site returns a promise;
-  `runtime.lastError` is gone. The same commit gives the Firefox suite the four
-  dApp round trips — `eth_requestAccounts`, `personal_sign`,
-  `eth_sendTransaction` and a closed approval window rejecting with EIP-1193
-  4001 — against a page and a JSON-RPC node served from loopback, which survives
-  `--network none`. **The premise of
-  [#153](https://git.eeqj.de/sneak/AutistMask/issues/153) does not survive that
-  harness**: Firefox's `browser.*` honours a trailing Chrome-style callback and
-  populates `runtime.lastError`, both measured directly on Firefox 153.0.3, and
-  all four flows pass against the unconverted code. What landed is a uniformity
-  and coverage change, not a repair of a broken target. `storageGet()` and
-  `storageSet()` **reject** where `storage.local` is absent rather than
-  resolving `{}` and a no-op write — they carry the wallet, and defaulting would

-- 2026-08-17: One transaction approval at a time. Populating in the background
-  before the window opens is what makes the displayed object the verified
-  object, and it also fixes the nonce: two `eth_sendTransaction` calls populated
-  concurrently took the same nonce from a node that had seen neither broadcast,

-  it; an approval whose window is gone and whose attempt has failed is settled
-  there rather than left waiting on a window that no longer exists, and an
-  approval window that could not be opened at all is answered with `-32603`
-  instead of holding the page's promise open. Signature approvals are not gated,
-  consuming no nonce. A collision that does happen is also reported accurately
-  now: a broadcast the node refused for the nonce, and an approval carrying a
-  nonce this worker has already broadcast for that address on that chain (caught
-  before the node is asked at all), both say the transaction did not reach the
-  network and to send it again, instead of warning that it may have sent. The
-  record is keyed by chain as well as address, because nonce spaces are per
-  chain and low nonces overlap across them. `already known` deliberately keeps
-  the ambiguous wording, because a node that says it has the transaction has it
-  ([#271](https://git.eeqj.de/sneak/AutistMask/issues/271)).
-- 2026-08-14: The parts of the
-  [#150](https://git.eeqj.de/sneak/AutistMask/issues/150) and
-  [#151](https://git.eeqj.de/sneak/AutistMask/issues/151) definition of done the
-  e2e suite did not cover are asserted. It had only shown that the two screens
-  open without throwing. Now: the Add Token round trip leaves the navigation
-  stack exactly as it found it, read out of extension storage rather than
-  inferred from which screen is up, so an orphaned entry — the second-order
-  damage of #150 — is caught where it happens rather than one Back press later;
-  a common-token quick-pick puts its contract address in the field; the native
-  ETH detail path renders with its own type, value and raw quantity and with the
-  token contract row still hidden, against a new `seedNativeTransfer` fixture,
-  since the normal-transactions endpoint answered `[]` unconditionally and there
-  was no non-ERC-20 row to open; and tapping the token contract address puts it
-  on the real clipboard, read back after a sentinel write. Each of the four was
-  demonstrated failing against a deliberately broken build
-  ([#188](https://git.eeqj.de/sneak/AutistMask/issues/188)).
-- 2026-08-14: `make check` does static analysis. `script/lint` ran
-  `prettier --check .`, byte-identical to `script/fmt-check`, so a wallet with
-  two shipped used-but-not-imported crashes behind it was green. ESLint is now
-  pinned in `package.json` with `@eslint/js` recommended as the base, flat
-  config in `eslint.config.js`, `no-undef` and `no-unused-vars` error-level, and
-  globals declared per tree — browser for the popup and content scripts, service
-  worker for `src/background/` and `src/shared/`, jest for `tests/`, node for
-  `build.js`. It found 41 unused bindings and 53 undefined identifiers; all are
-  fixed, and dropping a call to an unimported `foo()` into any `src/` file fails
-  `make lint`. Linting is also containerized now: `script/lint` builds the
-  Dockerfile's new `lint` stage, so the ESLint that decides whether this repo is
-  green is the pinned one and not the host's. The lint stage roughly doubles the
-  image build, so `script/test`'s hard timeout is now a bound on a hung suite
-  rather than a wall-clock budget: 30s on the host, where the suite runs in
-  about 8s, and `AUTISTMASK_TEST_TIMEOUT` raises it inside the image, where a
-  cold build pays install and contention costs the policy budget never described
-  ([#152](https://git.eeqj.de/sneak/AutistMask/issues/152)).
-- 2026-08-14: CI runs the browser end-to-end suites. `.gitea/workflows/e2e.yml`
-  runs `script/test-e2e` and `script/test-e2e-firefox` as two jobs on every
-  push, separate from `check`, so `make check` and its 20-second `make test` cap
-  are untouched. Every browser-level guarantee in this repo — the WASM-under-CSP
-  check, the recovery-phrase and private-key DOM wipes, the ConfirmTx spend
-  gate, the dApp approval round trips — was enforced only when a human
-  remembered to run it by hand. The suites could not run on the runner as they
-  stood: the runner executes a job in a container against the host's docker
-  daemon, so `docker run -v "$PWD:/work"` mounts an empty directory (measured),
-  and the runner image's node cannot install this repo's dependencies. Both
-  suites now ship the repo to the daemon as a build context and build the
-  extension inside the pinned image, so docker is the only prerequisite on a
-  runner or a laptop, and both run the image by ID rather than by tag so
-  concurrent clones cannot swap it. The jobs report rather than gate — this repo
-  configures no branch protection, and the Chrome suite is measurably flaky
-  under load, filed as [#287](https://git.eeqj.de/sneak/AutistMask/issues/287)
-  rather than papered over
-  ([#259](https://git.eeqj.de/sneak/AutistMask/issues/259)).
-- 2026-08-14: A background message handler that throws now rejects the page
-  instead of hanging it. `handleRpc(...).then(sendResponse)` had no `.catch()`,
-  and `sendResponse` is the only thing that settles the dApp's
-  `window.ethereum.request()` promise — so any throw inside `handleRpc` left
-  that promise pending forever, with no error and no timeout, indistinguishable
-  from a slow wallet. It now answers `{ code: -32603, message }` (the JSON-RPC
-  internal error EIP-1474 defines and EIP-1193 defers to; no EIP-1193 4xxx code
-  describes "the wallet broke" and none was invented) and logs the method and
-  the throw to the background console rather than swallowing them. The two async
-  IIFEs behind `AUTISTMASK_TX_RESPONSE` and `AUTISTMASK_SIGN_RESPONSE` were the
-  same shape one level down — every statement inside a `try`, but a throw out of
-  a `catch` block escaping unhandled — and each got a last-resort `.catch()`
-  settling the approval through `settleApproval()` and answering the popup. The
-  transaction one tracks which phase it escaped from and reports that, so an
-  escape before `broadcastTransaction()` says the request is gone rather than
-  that it may still have reached the network. Every other handler on the path is
-  synchronous. All four are driven by real failures — a rejecting storage read,
-  and a failure classifier that throws while classifying a genuine verification
-  or broadcast failure — and were demonstrated failing first, the RPC one with
-  `sendResponse` at zero calls
-  ([#280](https://git.eeqj.de/sneak/AutistMask/issues/280)).
-- 2026-08-14: Approving a site connection is no longer a race against the popup
-  closing. The decision now rides the approval port the popup already holds,
-  which is the same channel the close disconnects, so it is delivered ahead of
-  that disconnect however fast the teardown is; `windows.onRemoved` no longer
-  decides a site approval whose port is connected, since that event is ordered
-  against nothing either. Rejecting and closing without deciding both still
-  report a rejection, and the popup delays its own close by nothing. The e2e
-  harness's deferred-`window.close()` accommodation is gone with it, so the two
-  site-prompt tests now drive the shipped decide-then-close in a real Chromium;
-  against the unfixed code the approval came back to the page as

-//     isPhishingDomain() compares against.
-//   - entries that cannot be a hostname are dropped and counted. Upstream
-//     carries the odd URL-shaped entry (a path, a scheme); hostname matching can
-//     never match one, and once the artifact is hashes nobody can see that it is
-//     in there, so it is reported at vendoring time instead.
-//   - entries are hashed (see src/shared/domainHash.js) and sorted, and the
-//     digests are concatenated into one fixed-width string. Sorted is what makes
-//     the runtime lookup a binary search over that string, with no set to build

-# script/vendor-blocklist: refresh the vendored phishing blocklist at
-# src/shared/phishingBlocklist.json from its upstream source. Our own extension
-# to scripts-to-rule-them-all.
-#
-# This is build-time repo tooling and is not shipped. It is the one place in
-# this repo that names the upstream project, because a source reference that
-# does not say what the source is cannot be verified by anyone; the artifact it
-# writes carries no names at all (see src/shared/domainHash.js).
-# script/check-censored reads the name back out of this file rather than
-# repeating it, so it stays defined exactly once.
-#
-# Run it deliberately, not on every build: the output is committed, and the
-# extension does no runtime fetching, so the shipped list is exactly as fresh as
-# the last time someone ran this and landed the result. Re-run it, land the
-# diff, cut a release; that is the whole refresh path.
-#
-# Pinned by content hash, twice over, as REPO_POLICIES.md requires. The commit
-# below is an immutable ref — the upstream default branch moves several times a
-# day and cannot be pinned — and UPSTREAM_SHA256 is the sha256 of the bytes that
-# commit serves. A mismatch is a hard failure: a vendoring step that accepts
-# whatever it is handed is a supply-chain hole, and this one feeds a security
-# warning shown to users.
-#
-# To move the pin: pick the new commit, run this with the new UPSTREAM_COMMIT
-# and an UPSTREAM_SHA256 you have not yet updated, and it will print the hash it
-# actually got. Verify that hash against the source independently before
-# recording it. Never copy the "actual" line in on trust.

-// The two targets do not agree on the namespace, and they disagree about the
-// call shape only in which one is native. Chrome MV3 exposes `chrome.*`,
-// where tabs, windows and messaging take a trailing callback and report
-// failure through the global `chrome.runtime.lastError`. Firefox MV2 exposes
-// `browser.*`, where those same methods return promises — but, measured on
-// Firefox 153.0.3, it ALSO honours a trailing Chrome-style callback, returns
-// no promise when one is given, and populates `browser.runtime.lastError`.
-// The callback code that predated this module therefore ran on both, and
-// https://git.eeqj.de/sneak/AutistMask/issues/153 was filed on the belief
-// that it did not. This module exists for uniformity, not for repair: the
-// tree used to resolve the namespace with a ternary at six call sites and
-// then mix promise-form storage with callback-form messaging.
-//
-// The strategy is promises out, everywhere: one namespace, one call shape,
-// composing with the `async` handlers in the background. Callers `await`;
-// nothing outside this file has to know which browser it is running on.
-//
-// Two deliberate asymmetries, because they are what the browsers actually do

-//
-//  - Storage is called in its PROMISE form on both namespaces.

-//    already depends on that — src/shared/state.js has always awaited it.
-//    Wrapping it in a callback here would be a change, not a fix.
-//  - notify() sends without a callback. It is for a message whose answer
-//    nobody reads; appending a callback would only manufacture a
-//    lastError/rejection for a receiver that was never expected to reply.
-//
