fix: judge the symbol a user sees, not the bytes a contract returns (closes #260)

A token whose symbol is " ETH " missed KNOWN_SYMBOLS on all three surfaces
while HTML collapsed the padding and painted it as ETH next to the user's
real ETH. isSpoofedSymbol() now normalizes before the lookup: NFKC, every
Unicode format character removed wherever it sits, then trimmed, then
uppercased. All three surfaces inherit it unchanged.

Covered: ASCII and Unicode whitespace padding, zero-width and other
invisible format characters, and compatibility variants such as fullwidth
letters. Knowingly left open, and asserted as open in the suite: confusables
that are distinct letters (Cyrillic capital Ie), bidi reordering, and
interior whitespace, which renders differently and so is not the confusion.

No symbol in KNOWN_SYMBOLS or the bundled token list contains whitespace or
a non-ASCII character, so nothing legitimate is newly filtered; a test walks
the whole table and asserts it.

The balance list's token-type gate is now case-insensitive. It compared
exactly, so an explorer writing "erc-20" would silently drop a real holding
before any filter ran. Which types are admitted is unchanged.

-- 2026-08-12: The restored navigation stack is filtered against
-  `RESTORABLE_VIEWS` on load, truncated at the first entry the popup would not
-  render so that every surviving entry keeps the Back target it had. Back after
-  reopening can no longer land on a view the popup declined to restore, such as
-  `export-privkey` or `show-phrase`
-  ([#224](https://git.eeqj.de/sneak/AutistMask/issues/224)). Restorable views in

-- 2026-08-12: One wording for a rejected password on every screen that asks for
-  one — the send confirmation and the delete-wallet confirmation no longer say
-  "Wrong password." (a fragment, which `RULES.md` Language & Labeling forbids)
-  and the two reveal screens no longer say "not correct", so all five
-  `decryptWithPassword` call sites now show the sentence the dApp approval paths
-  introduced. Strings only, no behaviour change, and each error container
-  measured at a 360px viewport in the pinned Playwright container

-- 2026-08-12: Closed the empty-array hole in the end-to-end unstubbed-request
-  guard. `batch.every()` is vacuously true on `[]`, so a POST with body `[]` was
-  answered `200 []` instead of failing the suite; the guard now rejects an empty
-  batch, demonstrated green-before/red-after with a throwaway probe. The comment
-  claiming `postData()` returns `null` for undecodable bodies was corrected to
-  the two real paths — an absent or empty body decodes to `null`, a binary body
-  decodes lossily into invalid JSON
