fix: show balances and fees below 0.000001 ETH as nonzero on the send screens (closes #343)

The stored ETH balance and the send-confirm screen's fee were each cut to six
decimal places, so a value below 0.000001 read as 0.0, and the fee no longer
matched the approval screen's. The ETH balance is now stored exactly, and the
send screen's Current balance and the send-confirm screen's balance, fee,
reserve and insufficient-balance messages go through truncateAmountNeverZero(),
as the approval screen does. Token balances keep their six-decimal value: it is
also what leaves dust off the balance list, and keeps the string within the 18
decimals the balance check reads.

-  the site may ask again once the user has answered. A connection prompt whose

-  and the approval screen showed it as a bare number. `nonce` is no longer one

-  ([#402](https://git.eeqj.de/sneak/AutistMask/issues/402)). `allowedSites` and
-  `deniedSites` stored the hostname alone, so a grant to `https://dapp.example`
-  also authorised `http://dapp.example` and every port on that host, and the
-  prompts named only the hostname. Both lists now store and match the origin
-  (`scheme://host[:port]`), the key the connections approved without "Remember"
-  already used, in `src/background/index.js` and in Settings, whose site lists
-  and `AUTISTMASK_REMOVE_SITE` carry the origin too. The connection, transaction
-  and signature prompts show the origin. Entries saved by hostname before this
-  change are not migrated (pre-1.0): they match no site, and Settings lists them
-  until they are removed.
-
-- 2026-10-04: A page's request is credited only to the site the browser says
-  sent it ([#407](https://git.eeqj.de/sneak/AutistMask/issues/407)). Where the
-  browser does not give the sender's origin (Firefox before 126), the background
-  used the tab's page, so a frame from another site would have been treated as
-  the site embedding it, and with no tab it used an origin the page wrote into
-  the message. It now uses the URL of the frame that sent the message, and
-  refuses the request with code 4100 when the browser gives neither. The content
-  script no longer writes an origin into the message.
-
-- 2026-10-04: `make test` takes 8-13s on the shared build host, down from
-  17-25s, measured in alternating runs before and after the change
-  ([#428](https://git.eeqj.de/sneak/AutistMask/issues/428)). Each popup boot in
-  the tests (`tests/support/popupBoot.js`) resets jest's module registry so that
-  everything under `src/` loads fresh, and that also reloaded `ethers`,
-  `libsodium-wrappers-sumo`, `qrcode` and `ethereum-blockies-base64` every time.
-  Those four libraries are now loaded once per test file and handed to every
-  boot. No test or assertion changed.
-
-- 2026-10-04: A token whose scale is unknown reads the same on the Send screen
-  as on the confirmation screen
-  ([#377](https://git.eeqj.de/sneak/AutistMask/issues/377)). When two addresses'
-  explorer reports disagree on a token's `decimals`, the Send screen showed the
-  stored figure while the confirmation screen it leads to said
-  `unknown (SYMBOL)`; both now say `unknown (SYMBOL)`, from one function in
-  `src/popup/views/send.js`. The confirmation screen's fee-unknown message names
-  its cause: for an unknown scale it says the wallet does not know how many
-  decimal places the token uses and that the transaction cannot be sent, instead
-  of asking the user to go back and try again, which cannot help. For any other
-  cause it is unchanged.
-
-- 2026-10-04: A Uniswap V2 exact-out swap (Universal Router command `0x09`) is
-  decoded on the approval screen
-  ([#283](https://git.eeqj.de/sneak/AutistMask/issues/283)). `decode()` in
-  `src/shared/uniswap.js` had no arm for it, so the screen named the step and
-  showed no token or amount. The input side is the path's first token with
-  `amountInMax`, the output side the last token with `amountOut`. When the
-  transaction has such a step, the `Amount` figure reads `Up to <amount>`,
-  whichever step set it, there and on the wait, success and error screens,
-  except where it reads `Unlimited` (an unbounded `PERMIT2_PERMIT`, or any
-  amount at or above the `uint160` maximum) or `All available (V4 open delta)`.
-  In every swap, `UNWRAP_WETH` makes `Token Out` ETH only when the output side
-  is WETH, on mainnet or Sepolia, or when no step set the output side; otherwise
-  `Token Out` and `Min. received` keep the output side's own token and figure.
-  V3 exact-out (`0x01`) is still not decoded.
-
-- 2026-10-04: `make test` runs jest in three worker processes
-  ([#426](https://git.eeqj.de/sneak/AutistMask/issues/426)). The `test` and
-  `test:verbose` scripts in `package.json` ran `jest --forceExit`, which starts
-  one worker per CPU core: about 47 processes and 7-8 GiB per run on the shared
-  48-core build host. They now pass `--maxWorkers=3`, and the suite takes 23-29s
-  there: inside the 30-second cap in `script/test`, which is unchanged, but not
-  by much, because `tests/persistedFieldContract.test.js` alone takes most of it
-  ([#428](https://git.eeqj.de/sneak/AutistMask/issues/428)). One or two workers
-  went past the cap. `make check`, the pre-commit hook and `script/cibuild` all
-  run the suite through these scripts.
-
-- 2026-10-04: The error container on each dApp approval screen keeps its height
-  when an error appears
-  ([#297](https://git.eeqj.de/sneak/AutistMask/issues/297)). `#approve-tx-error`
-  and `#approve-sign-error` reserved 20px, but their border and padding took
-  10px of it, so a one-line error grew them to 26px and pushed the buttons below
-  down 6px. They now reserve 30px. A new test in `tests/e2e/run.js` shows each
-  of the six password error containers on its own screen, empty and then with an
-  error, and fails if one changes height or the element below it moves. Some of
-  the longer messages these two containers can show still take two lines.
-
-- 2026-10-04: A transaction with no `to` says "This transaction creates a new
-  contract. It has no recipient." on its recipient line and in its transaction
-  history row ([#250](https://git.eeqj.de/sneak/AutistMask/issues/250)). The
-  wait, success and error screens, the transaction detail view and the history
-  rows on Home, AddressDetail and AddressToken showed a blank address there,
-  with a colour dot whose colour was `undefined`; the approval screen showed
-  "(contract creation)". A transaction with a real `to` is unchanged.
-
-- 2026-10-04: The Send and confirmation screens no longer show an ETH balance, a
-  token balance or a network fee below 0.000001 as zero
-  ([#343](https://git.eeqj.de/sneak/AutistMask/issues/343)). The stored balances
-  (`src/shared/balances.js`) and the confirmation screen's fee were each cut to
-  six decimal places by a rule of their own, and a token holding cut to zero was
-  dropped. Balances are now stored exactly, whatever decimals a token declares,
-  and every nonzero token holding is kept; the balance check reads a token
-  balance to its first 18 places, the most an amount can have. The balance
-  lists, the send-screen token selector, the address total and the
-  remove-address warning leave out a holding below 0.000001 themselves, as
-  before. The Send screen's `Current balance`, and the confirmation screen's
-  balance, fee, reserve and insufficient-balance messages, go through
+- 2026-10-04: The Send and confirmation screens no longer show an ETH balance or
+  a network fee below 0.000001 as `0.0`
+  ([#343](https://git.eeqj.de/sneak/AutistMask/issues/343)). The stored ETH
+  balance (`src/shared/balances.js`) and the confirmation screen's fee were each
+  cut to six decimal places by a rule of their own. The ETH balance is now
+  stored exactly, and the Send screen's `Current balance`, and the confirmation
+  screen's balance, fee, reserve and insufficient-balance messages, go through
   `truncateAmountNeverZero()` in `src/shared/amountDisplay.js`, the helper the
-  approval screen already used. The confirmation and approval screens both
-  render the fee through `formatFee()` in `src/popup/views/helpers.js`, which
-  prices the exact fee in USD, so the same fee reads the same on both, USD value
-  included.
-
-- 2026-10-04: The flash line keeps to the one line it reserves at any message
-  length ([#252](https://git.eeqj.de/sneak/AutistMask/issues/252)). A message
-  that wrapped pushed the whole screen below it down. `#flash-msg` no longer
-  wraps: text too long for the line is cut with an ellipsis, and `showFlash()`
-  puts the whole message in the line's title. Every message is also reworded to
-  at most 50 characters so none is cut; none carries a wallet name or text from
-  a server, and the add-token screens flash a fixed line for any error other
-  than a contract that is not a token. A new test in `tests/e2e/run.js` puts a
-  message several lines long on the line and fails if the line or the screen
-  below it moves. The two approval-screen error boxes are left to
-  [#297](https://git.eeqj.de/sneak/AutistMask/issues/297).
-
-- 2026-10-04: A method the wallet does not implement is refused with EIP-1193
-  code `4200` ([#279](https://git.eeqj.de/sneak/AutistMask/issues/279)). The
-  background's `Unsupported method: <method>` error carried no code, so a site
-  probing for an optional method could not tell "not implemented" from "the call
-  failed". The message is unchanged; the background's other errors with no code
-  are untouched.
-
-- 2026-10-04: Settings lists the sites connected without "Remember", and
-  removing a site there disconnects it
-  ([#406](https://git.eeqj.de/sneak/AutistMask/issues/406)). Such a connection
-  lives only in the background's in-memory `connectedSites` map, so Settings
-  never showed it and the user could not end it; `AUTISTMASK_REMOVE_SITE`, sent
-  on every remove, did nothing. Settings now asks the background for those sites
-  (`AUTISTMASK_GET_CONNECTED_SITES`) and lists them under Connected Sites.
-  Removing a site from Allowed Sites or Connected Sites drops its remembered
-  entry under every address and sends `AUTISTMASK_REMOVE_SITE` with the
-  hostname; the background deletes every `connectedSites` entry for that
-  hostname and sends `accountsChanged` with an empty list to its open tabs. Only
-  the extension's own pages may send either message. Removing a denied site no
-  longer sends it, since forgetting a refusal ends no connection.
-- 2026-10-04: Removing an address or deleting a wallet ends every site
-  connection approved without "Remember" for the addresses removed
-  ([#245](https://git.eeqj.de/sneak/AutistMask/issues/245)). Such a connection
-  lives only in the background's in-memory `connectedSites` map. Both removal
-  paths dropped the remembered `allowedSites`/`deniedSites` entries, but nothing
-  told the background, so its entry was cleared only as a side effect: every
-  change of active address empties the whole map, and removing the active
-  address changes it. `dropSitePermissions()` in `src/shared/walletDelete.js`,
-  shared by both paths, now also sends `AUTISTMASK_ADDRESSES_REMOVED` with the
-  removed addresses, and the background deletes their `connectedSites` entries;
-  only the extension's own pages may send it.

-- 2026-09-21: `README.md` no longer says a genuine zero always renders `0.0000`
-  ([#369](https://git.eeqj.de/sneak/AutistMask/issues/369)). The amount rule
-  still renders one as `0.0000`, but two swap lines say a zero in words instead:
-  `Min. received` reads `None (no minimum guaranteed)` for a zero minimum, and
-  `Amount` reads `All available (V4 open delta)` when the amount it shows is a
-  V4 exact-in `amountIn` of zero. A new list says what the decoded ERC-20 and

-  `All available (V4 open delta)` and `None (no minimum guaranteed)`, which a
