fix: an open popup moves to the recovery screen when its profile becomes unreadable (closes #373)

A popup already open when the stored profile became unreadable stayed on the
last good profile until reopened. Every save already runs the check loadState()
runs at open; a save refused by it now raises the recovery screen, stops the
ten-second refresh, and passes the screen to showView(), which runs the leave
cleanup of the screen it replaces and records it as the current view. From
then on showView() shows nothing else, so a transaction wait or a later save
cannot take the user off it or clear an export or a typed confirmation. Any
other failed save keeps the "NOT SAVED" banner. The popup test harness now
honours clearInterval().

-  ([#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

-  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

-  ([#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

-- 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.
+  Every save already ran the check the popup runs at open; a save that fails
+  that check now raises the recovery screen and stops the ten-second refresh, so
+  the popup finds the record at the next navigation or 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 can replace it, and a later
+  save or a transaction wait that ends does not clear an export or a typed
+  confirmation. Any other failed save still gets the banner and leaves the
+  screen alone.
 - 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

-// The native token's label on the screens that show a native amount.

-// src/shared/networks.js gives each network a nativeCurrency, `ETH` on mainnet
-// and `SepoliaETH` on Sepolia, and nothing read it: every screen wrote a
-// hardcoded "ETH", so on Sepolia the balance, the value and the fee all read
-// ETH (https://git.eeqj.de/sneak/AutistMask/issues/372). Each line is asserted
-// on both networks, through the real Send, confirmation and approval screens,
-// with only the node and the DOM stubbed. So is that a token cannot pass for
-// the native token by reporting its label, and that a transaction's figures
-// carry its own network's label when another network is active.
