test: the e2e suite waits for each save before it closes the popup (closes #446)

The Settings round trip switched the theme and the network and closed
the popup at once. A close before the change handler's save lands loses
the switch, and the suite then ran on Sepolia.

tests/e2e/run.js now has one helper that polls a field of the stored
record until it holds the expected value, in place of the wait that
only read viewStack. Each Settings switch and spam-filter toggle waits
for its save, the recovery-phrase reopen waits for its saved view, and
reopenPopup() waits until the view it expects to reopen on is the saved
one.

-  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.

-  TransactionDetail opened from the token screen leaves that screen on the

-  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

   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

-- 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.
+  waits until the view it expects to reopen on is the saved one. A change made
+  while an earlier save from the same page is still running is lost even without
+  a close; that is [#448](https://git.eeqj.de/sneak/AutistMask/issues/448).
