chore: remove dead exports and share copied view helpers (closes #168)

AddressDetail and AddressToken defined their own isoDate() and
timeAgo(), hiding the shared pair in helpers.js, so a fix there would
not have reached them. The copies were identical and are deleted;
blockieHtml() and tokenLabel(), each defined twice, move to helpers.js.
A new test shows the history rows and the transaction detail view
write the time with the shared pair.

Deleted as never called: explorerLink(), ETHEREUM_SEPOLIA_CHAIN_ID,
getWalletValue() and getTotalValue() with their tests. Home's "Total:"
is the active address's total, as README.md already says.
addressColor() and etherscanAddressUrl() are no longer exported.

 # Completed Steps
 
-- 2026-10-05: `PROXY_METHODS` in `src/background/index.js` no longer lists
-  `eth_chainId` and `net_version`
-  ([#326](https://git.eeqj.de/sneak/AutistMask/issues/326)). `handleRpc` answers
-  both itself before its proxy branch, so the list named two methods that are
-  never sent to the RPC endpoint. No other entry is answered earlier.
-  `tests/proxyMethods.test.js` sends every listed method from a page and fails
-  on any that does not reach the RPC endpoint.
-
-- 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.
-
-- 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
