Add account switching and watch-only wallets

Accounts: a switcher (header chip → Accounts screen) lets you keep
several wallets loaded and flip between them without re-importing. Per
the chosen model, full (seed) accounts live only in sessionStorage —
ephemeral, no seed on disk; watch-only accounts (no seed) are persisted
in localStorage and reload across restarts. enterWallet is refactored
around an accounts list (add/switch/remove/lock); Add wallet reaches the
unlock screen with a back button.

Watch-only: load any wallet from its account xpub/zpub (parseAccountKey
normalizes zpub→xpub; the existing public-derivation path yields the
same addresses). Signing is blocked, the Send tab and seed/sync/offline
cards are hidden, and a watch-only note is shown. Settings gains a
"Public key" card (export this wallet's zpub) so it can be watched
read-only elsewhere.

Password-encrypted persistence for full accounts is the planned next
step. New strings translated across all 19 locales.
