chore: escape every value the views write as markup, and cut symbols on code points (closes #329 )

The token screen's decimals and holder count, the ETH price, every address total and each balance row's USD value went into innerHTML unescaped, against the rule at the top of src/popup/views/helpers.js. 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, not UTF-16 units, so the cut never leaves half of an emoji, which rendered as U+FFFD. explorerLink() was already removed on next.

 # Completed Steps

- 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
-  Add Token by its contract address is listed on the address screen;
-  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.
