harden: show a personal message's hex and its text in byte order, hidden characters marked (closes #403)

The signature screen showed only the text a personal message decodes
to, with bidirectional, right-to-left and zero-width characters acting
on it, so a site could make the message read differently from the
bytes that are signed, and a message that was not hex was decoded into
NUL characters. The screen now shows the hex as "Raw data" alongside
the text, lays the text out left to right in byte order, and shows each
control character, line and paragraph separator, and character that
paints nothing (the set src/shared/symbolSpoof.js already strips) as a
U+XXXX mark. A message is hex when getBytes, which signing uses, reads
it; one that is not cannot be signed, so it is shown as plain text with
"Sign" disabled.

-- 2026-10-05: Every CI job has a `timeout-minutes` cap

-  slowest cold-cache run. A hung build or browser now ends its job instead of

-
-- 2026-10-05: The popup's Content Security Policy no longer allows inline style
-  ([#328](https://git.eeqj.de/sneak/AutistMask/issues/328)): `style-src` is
-  `'self'` in both manifests, pinned in `tests/manifest.test.js`. The 42
-  `style="..."` attributes in `src/popup/index.html` and in the markup the view
-  helpers build are now Tailwind classes, each computing to the value it
-  replaced. The 16 address dot colours are written out as whole classes, because
-  Tailwind builds only the classes it finds in the source. The Settings debug
-  well is shown and hidden with the `hidden` class, since clearing an inline
-  `display` no longer uncovers it. Script that sets `element.style` is
-  unaffected.
-
-- 2026-10-05: `.prettierignore` no longer lists an AI vendor's tool directory
-  ([#363](https://git.eeqj.de/sneak/AutistMask/issues/363)). The directory is
-  not tracked, so the line ignored nothing.
-
-- 2026-10-05: The Chrome end-to-end suite drives both ways the wait for a
-  transaction's receipt ends on the error screen
-  ([#315](https://git.eeqj.de/sneak/AutistMask/issues/315)): lookups that still
-  find no receipt 60 seconds after the broadcast end it with the timeout
-  message, and six lookups that fail in a row end it with the message naming the
-  unreachable network. Done then returns to the address screen. Both cases wait
-  in real time, about a minute each. Playwright's clock would apply to every
-  later test in the run and cannot be removed, and moving the stored broadcast
-  time back can be undone by the save the popup makes every ten seconds.
-
-- 2026-10-05: The Chrome end-to-end suite covers the last of the
-  [#150](https://git.eeqj.de/sneak/AutistMask/issues/150) and
-  [#151](https://git.eeqj.de/sneak/AutistMask/issues/151) items
-  ([#295](https://git.eeqj.de/sneak/AutistMask/issues/295)): a token added on

-  TransactionDetail opened from the token screen leaves that screen on the
-  persisted navigation stack, and Back returns to it; and the token contract row
-  links to the explorer's token page, read off the link rather than followed.
-  The network stub answers `symbol()` and `name()` for the stub token, which
-  adding it reads.
-
-- 2026-10-05: Each control that leads to a signature or to the private key has a
-  test that it refuses a defective wallet before asking for a password
-  ([#254](https://git.eeqj.de/sneak/AutistMask/issues/254)): Send on the main,
-  address and token screens, Export Private Key, and both approval screens, as
-  drawn and as clicked. Send on the confirmation screen refuses it too now,
-  because the popup reopens onto that screen from a saved view. The comments
-  that said the wallet's key cannot be derived now say that
-  `getSignerForAddress` refuses it, and the module comment in
-  `src/shared/walletDefects.js` names both earlier import paths.
-
-- 2026-10-05: The Chrome end-to-end suite drives the private key export screen
-  as it drives the recovery phrase screen
-  ([#253](https://git.eeqj.de/sneak/AutistMask/issues/253)): the correct
-  password shows the key, leaving by the settings gear empties the screen, and
-  leaving while the password is still being checked never puts the key on it.
-  The cases use the imported key wallet rather than the HD one. Leaving drops
-  the address the screen was showing, and an HD wallet's key cannot be derived
-  without it, so on an HD wallet a late decrypt fails by itself and would never
-  exercise the check that discards it. The screen cannot yet be opened twice in
-  one popup session ([#460](https://git.eeqj.de/sneak/AutistMask/issues/460)),
-  so the cases reopen the popup before the second open.
-
-- 2026-10-05: The StateRecovery screen is driven in a real browser under the
-  shipped CSP, in both end-to-end suites
-  ([#361](https://git.eeqj.de/sneak/AutistMask/issues/361)). A stored record
-  this build cannot read opens the popup on it; its export text box holds the
-  record exactly as stored; a near-miss confirmation phrase erases nothing; and
-  the exact phrase erases the record and reloads into Welcome. The cases run
-  before any wallet exists: with no wallet nothing saves on a timer, so no save
-  can write a good record over the unreadable one, and the erase leaves the
-  popup on Welcome for wallet creation.
-
-- 2026-10-05: Escaping in the popup's views follows its own rule with no
-  exceptions ([#329](https://git.eeqj.de/sneak/AutistMask/issues/329)). The
-  decimals and holder count on a token's screen, and every USD figure (the ETH
-  price, each total and each balance row's value), went into `innerHTML`
-  unescaped; they are escaped now. None could carry markup, but `formatUsd()`
-  writes a value under a cent as `< $0.01`. `displaySymbol()` counts a symbol in
-  code points rather than UTF-16 units, so a cut never splits an emoji into a
-  half that renders as U+FFFD. `explorerLink()`, also named in the issue, was
-  already removed by [#168](https://git.eeqj.de/sneak/AutistMask/issues/168).
-
-- 2026-10-05: A Chrome end-to-end test that fails no longer takes later tests
-  down with it ([#318](https://git.eeqj.de/sneak/AutistMask/issues/318)). Each
-  test that turns a fixture switch on for itself alone (a held or failing gas
-  estimate, a seeded native transfer or receipt, a token's lying `decimals()` or
-  markup symbol) turns it off again in a `finally`, and the two tests that drive
-  the popup's own send end on the address screen whether they pass or not,
-  reopening the popup to leave a wait for a receipt. The lying-`decimals()` test
-  checks that nothing was broadcast as soon as the send ends, before it waits
-  for the failure screen, so a broadcast fails it in seconds rather than after a
-  60-second wait. The fixture's `decimals()` override tells 0 from no override,
-  so a token with no decimal places can be fixtured.
-
-- 2026-10-05: Chrome draws the popup in its monospace font
-  ([#418](https://git.eeqj.de/sneak/AutistMask/issues/418)), as Firefox does.
-  Chrome adds a stylesheet of its own to extension pages that sets the font on
-  `body`, and it beat Tailwind's `font-mono`: Tailwind 4 puts its classes in a
-  cascade layer, and a rule outside any layer wins over them. `body` now carries
-  `font-mono!`, which marks the class important. Both end-to-end suites check
-  the popup's font. The same stylesheet also makes Chrome draw the popup's text
-  at 12px rather than the 14px `text-sm` asks for; that is unchanged, and filed
-  as [#456](https://git.eeqj.de/sneak/AutistMask/issues/456).
-
-- 2026-10-05: Dead code removed and copied view helpers shared
-  ([#168](https://git.eeqj.de/sneak/AutistMask/issues/168)). AddressDetail and
-  AddressToken each defined their own `isoDate()` and `timeAgo()` in place of
-  the ones in `src/popup/views/helpers.js`, so a fix to the shared pair would
-  not have reached them. The copies were identical; every screen now uses the
-  shared pair. `blockieHtml()` and `tokenLabel()`, each defined twice, live in
-  `helpers.js` too. Removed as never called: `explorerLink()` (the views build
-  explorer links with `explorerUrl()`), `ETHEREUM_SEPOLIA_CHAIN_ID` (the chain
-  id lives in `src/shared/networks.js`), and `getWalletValue()` and
-  `getTotalValue()`: Home's "Total:" is the active address's total, as
-  `README.md` says. `addressColor()` and `etherscanAddressUrl()` are no longer
-  exported. Nothing the user sees changed.
-
-- 2026-10-05: A prompt raised while another approval window has focus opens a
-  window of its own ([#290](https://git.eeqj.de/sneak/AutistMask/issues/290)).
-  The background centred each approval window on the last focused window, which
-  could be an earlier approval window still open; headless Chrome reports one as
-  1280x720, so the new window came out where the browser refused to create it,
-  and the request failed with no window at all. It now centres only on a browser
-  window, and when the browser refuses the position it asks again without one
-  and lets the browser place the window. In the Chrome end-to-end suite a test
-  could raise its prompt while the previous test's window was still closing, and
-  then either hit that refusal or take the closing window for its own. After a
-  test that passed, the runner now waits a few seconds for approval windows to
-  close and fails the test if one is still open; after a test that failed, it
-  closes them.
-
-- 2026-10-05: The Send screen has a "Max" button
-  ([#198](https://git.eeqj.de/sneak/AutistMask/issues/198)). Emptying an ETH
-  address took guessing an amount and being refused by the confirmation screen's
-  balance check. Max fills in a token's whole balance, cut to the 18 decimal
-  places the confirmation screen accepts, or for ETH the exact balance minus the
-  fee reserve that check gates on, never the four-decimal balance shown; a fee
-  estimate that finishes after the Send screen was left, or its address, holding
-  or recipient changed, fills nothing in. The confirmation screen works a max
-  ETH amount out again from its own fee estimate and signs it with that
-  estimate's fee fields: fetched again at signing, a fee that had risen since
-  would leave amount plus fee above the balance, and the node would refuse the
-  send. A token's maximum is still refused when ETH cannot pay the fee. Where
-  there is nothing to fill in, a flash message says why.
-
-- 2026-10-05: A token scale of zero decimals is tested
-  ([#325](https://git.eeqj.de/sneak/AutistMask/issues/325)).
-  `resolveTokenDecimals()` already used a scale of 0 from the bundled list or
-  from a tracked token, but no test said so: turning either of its `d !== null`
-  checks into a plain truthiness check left every test green while a
-  zero-decimal token fell through to the next source, or to "decimals unknown".
-  The approval tests now assert a scale of 0 from each of those two sources,
-  both where it is resolved and on the approval screen's Amount line. The second
-  half of the issue, one shared `toDecimals()`, had already landed with
-  [#349](https://git.eeqj.de/sneak/AutistMask/issues/349).
-
-- 2026-10-05: The e2e suite waits for a save to land before it closes the popup
-  ([#446](https://git.eeqj.de/sneak/AutistMask/issues/446)). The Settings round
-  trip switched the theme and the network and closed the popup at once, and a
-  close before the save lands loses the switch; with the network left on
-  Sepolia, a dozen later tests failed too. Each Settings switch and spam-filter
-  toggle is now waited for in storage before the close, and `reopenPopup()`
-  waits until the view it expects to reopen on is the saved one. The restore
-  half of the round trip and the second filter toggle change a setting right
-  after a reopen, while the reopened popup's own saves may still be running;
-  they rely on the fix for
-  [#448](https://git.eeqj.de/sneak/AutistMask/issues/448).
-
-- 2026-10-05: A change made while an earlier save from the same page is still
-  running is stored ([#448](https://git.eeqj.de/sneak/AutistMask/issues/448)).
-  `saveStateOnce()` took its baseline from the page's state after the write, so
-  a change made while the save waited on storage counted as already stored and
-  the save queued after it wrote nothing. A setting changed during the read was
-  lost; so was a wallet added, a site revoked or an endpoint changed during the
-  write, and a wallet deleted then stayed in storage. The save now copies the
-  page's fields when it starts, writes from that copy, and keeps the copy as the
-  baseline.
-
-- 2026-10-05: The extension no longer opens a window for a site-connection
-  prompt already answered
-  ([#287](https://git.eeqj.de/sneak/AutistMask/issues/287)). When the prompt was
-  decided before the toolbar popup raised for it had loaded, that popup was torn
-  down, `chrome.action.openPopup()` rejected, and the background opened its
-  fallback window for the answered approval and then removed it. In the Chrome
-  end-to-end suite the next test could take that window for its own prompt and
-  lose it under its wait. `openApprovalWindow()` now opens nothing for an
-  approval that is no longer pending. The blocklist test's Reject, whose window
-  closes itself, is clicked as the other site Reject is, with the click
-  witnessed. Making `e2e-chrome` a required check is still blocked: other
-  reports of the Chrome suite failing under load are open, among them
-  [#290](https://git.eeqj.de/sneak/AutistMask/issues/290) and
-  [#446](https://git.eeqj.de/sneak/AutistMask/issues/446), as `README.md` says.

-- 2026-10-05: The lost-password delete confirmation refuses an empty field and
-  ignores characters that paint nothing
-  ([#336](https://git.eeqj.de/sneak/AutistMask/issues/336)). A wallet named only
-  with spaces compared equal to an empty field, so typing nothing would have
-  deleted it, and a zero-width space in a name made the name impossible to type
-  back. An empty field is now refused whatever the name is, the same invisible
-  characters `src/shared/symbolSpoof.js` strips are removed from both sides, and
-  a name that shows nothing is shown and typed back as "Wallet N".
-
-- 2026-10-05: A `holders_count` that is not a whole number in plain digits is
-  unknown, not read in part
-  ([#251](https://git.eeqj.de/sneak/AutistMask/issues/251)). `parseInt` read
-  `1,000` as 1, `0x10` as 0 and `1e3` as 1, a reported low count that hides the
-  token in the transaction history and the send-screen token selector. A count
-  above `Number.MAX_SAFE_INTEGER` is unknown too, not rounded or `Infinity`. The
-  balance list's `holders !== null` check, which did nothing, is dropped.
-  `README.md` and `docs/README.md` now say how each filter treats an unknown
-  count and that the token screen leaves out its "Holders:" row then, and
-  `README.md` lists `src/shared/holders.js`.
-
-- 2026-10-04: A popup boot in the tests loads transactions without failing
-  ([#429](https://git.eeqj.de/sneak/AutistMask/issues/429)). The stand-in for
-  `filterTransactions` in `tests/support/popupBoot.js` returned a bare list,
-  while the real one returns `{ transactions, newFraudContracts }`, so every
-  boot onto Home, AddressDetail or AddressToken failed inside its transaction

-- 2026-10-04: The native token's label follows the network
-  ([#372](https://git.eeqj.de/sneak/AutistMask/issues/372)). `networks.js` gives
-  each network a `nativeCurrency` and nothing read it: every screen wrote `ETH`,
-  so on Sepolia the balance, the value and the fee all read `ETH`. Every native
-  figure now reads `nativeCurrency`, which is `ETH` on mainnet and `SepoliaETH`
-  on Sepolia: the balance lists, Send and confirmation screens and the
-  contract-recipient warning the active network's; the approval, wait, success,
-  error and transaction detail screens, the transaction history and the refusal
-  of a fee above the limit that of the network the transaction's chain id names.
-  A token claiming any network's `nativeCurrency` is dropped as a fake, as one
-  claiming `ETH` already was, and the transaction detail screen calls an entry a
-  token transfer when it has a token contract, not by its symbol.
-- 2026-10-04: A popup that is already open when the stored profile becomes
-  unreadable moves to the recovery screen
-  ([#373](https://git.eeqj.de/sneak/AutistMask/issues/373)). It used to stay on
-  the last good profile, with the "NOT SAVED" banner at most, until reopened.
-  Every save already ran the check the popup runs at open, so the popup finds
-  the record at the next navigation or ten-second refresh, whether or not the
-  network answers; a save that fails that check now raises the recovery screen
-  and stops the refresh. The screen it replaces is left as any navigation leaves
-  it, so a revealed phrase or key or a typed password is wiped. Once up, nothing
-  else in that popup can replace it, and a later save or a transaction wait that
-  ends does not clear an export or a typed confirmation. It is never saved as
-  the current view, so a popup opened after the record is erased in another
-  window opens normally. Any other failed save still gets the banner and leaves
-  the screen alone.
-- 2026-10-04: A swap whose deadline is later than a JavaScript date can hold is
-  decoded ([#437](https://git.eeqj.de/sneak/AutistMask/issues/437)). A date
-  reaches only to 275760-09-13, so a later deadline, such as the `uint256`
-  maximum, made the `Deadline` line throw, and the approval screen showed the
-  swap as an undecoded contract call with nothing saying why. That line now
-  reads `After 275760-09-13 00:00:00 (no deadline in practice)`.
-- 2026-10-04: The swap decoder reads two router zeros the way the router does
-  ([#415](https://git.eeqj.de/sneak/AutistMask/issues/415)). A V2 exact-in
-  `amountIn` of zero means an earlier step already sent the tokens to the pair;
-  `Amount` showed `0.0000` for it and now reads
-  `Whatever an earlier step sent to the pair (V2 already paid)`. A
-  `BALANCE_CHECK_ERC20` with a zero `minBalance` guarantees nothing, yet it
-  replaced the minimum an earlier swap step stated, so `Min. received` read
-  `None (no minimum guaranteed)`; it now sets the output side only when that
-  side holds no minimum at the point the check is reached. A nonzero
-  `minBalance` still sets the output side.
 - 2026-10-04: The signature screen shows a personal message as the bytes that
   are signed ([#403](https://git.eeqj.de/sneak/AutistMask/issues/403)). It
   showed only the decoded text, with bidirectional and zero-width characters

-  scale ([#350](https://git.eeqj.de/sneak/AutistMask/issues/350)). The shared
-  scale check `toDecimals()` accepted any `uint8`, but `formatUnits()` throws

-  undecoded, with nothing saying why. The check now stops at 80, and both
-  approval paths show the base-unit amount with the scale stated as unknown. The
-  balance list and the history list use the same check, so the same token no
