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.

-  page's fields when it starts, writes from that copy, and keeps the copy as the

-
-- 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
-  loading and logged `loadHomeTxs failed` or `loadTransactions failed`; the rest
-  of that code never ran. The stand-in now returns the real shape, and
-  `tests/persistedFieldContract.test.js` boots onto each of the three and
-  asserts neither message is logged. `make test` time did not change measurably.
-
-- 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

   characters that paint nothing are shown as `U+XXXX` marks, and a message that
   is not hex by the rule signing reads it with is shown as plain text with
   "Sign" disabled, since such a message has no bytes to sign.
-- 2026-10-04: A token that reports more than 80 decimal places has no known
-  scale ([#350](https://git.eeqj.de/sneak/AutistMask/issues/350)). The shared
-  scale check `toDecimals()` accepted any `uint8`, but `formatUnits()` throws
-  above 80, so such a token left a swap or an ERC-20 call on the approval screen
-  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
-  longer stops an address's token balances from refreshing or its history from
-  loading.
-- 2026-10-04: Debug mode no longer writes RPC API keys to the console
-  ([#410](https://git.eeqj.de/sneak/AutistMask/issues/410)). `debugFetch` logged
-  every request's full URL and body, so an RPC endpoint with a key in its path
-  or query string printed that key on every request. It now logs the HTTP
-  method, the URL's origin and, for a JSON-RPC call, the method name. The
-  balance refresh and token lookup log the RPC endpoint by its origin too. A
-  failed RPC call's error line prints the error's short message, which names the
-  HTTP status, not its full message, which carries the request URL. A failed
-  endpoint check in settings names the endpoint by its origin, not the `fetch`
-  error's message, which carries the whole URL, password included, for a URL
-  with a user name and password. The README's DEBUG Mode Policy says what debug
-  mode logs.
