Completes todo #15. On login, if an encrypted copy of the user's storage and/or
wallet settings exists on their Nostr account — and this device hasn't already
opted in — offer to restore it.
- js/nostr/encryptedSync.js: exists(dTag) — cheap list-only existence peek (NO
decrypt, so it doesn't spend the signer budget); decryption only on accept.
- storage/walletSyncService: hasRemote() wrappers over exists().
- js/services/settingsRestorePrompt.js: one-time per-pubkey offer. Only prompts
for items with a remote copy not already enabled locally; if nothing remote
exists it does NOT consume the one-time offer (a note published later can still
prompt next login). On accept, pulls + applies.
- app.js handleLoginModalSuccess: fires maybeOfferSettingsRestore(pubkey) after
login, deferred ~2s so relays connect; best-effort, never blocks login; toasts
on restore.
tests/settings-restore-prompt.test.mjs: offer+restore-only-remote-items, decline,
prompt-once, skip-already-enabled, don't-consume-when-empty. Mutation-verified.

Adds encrypted cross-login sync for the NWC wallet connection (todo #15),
reusing the encrypted-sync core under d-tag "bitvid:nwc".
- js/services/settingsSyncFlags.js: shared per-pubkey opt-in flag store
(storage/wallet); storageSyncService refactored onto it (identical behavior,
tests still green).
- js/services/walletSyncService.js: factory (NwcSettingsService is per-app, not a
singleton). push() syncs the current nwcUri (+defaultZap); pull() applies it via
updateActiveNwcSettings; disable() wipes the note.
- Wallet pane (components/profile-modal.html + ProfileWalletController): opt-in
toggle + Restore button + a strong SPENDING warning, shown only when a signer
can encrypt. Enabling requires an explicit window.confirm (the URI can spend).
Re-pushes on save when enabled; and on wallet DISCONNECT while synced it clears
the note so a removed spending URI doesn't linger (encrypted) on relays.
tests/wallet-sync-service.test.mjs: enable-pushes-uri, pull-restores-via-
updateActiveNwcSettings, disable-clears, no-wallet-doesn't-publish. Mutation-
verified (skip-apply + skip-clear both fail).
