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).

Wires the encrypted-sync core (0abb82b9) to the live client + active signer and
adds the storage-credential sync service. No UI yet — the Storage pane toggle is
the next increment.
- js/nostr/encryptedSyncFacade.js: default encryptedSync instance bound to
nostrClient (write set via getDeletePublishRelays, read relays, pool) and the
active signer's signEvent. Keeps the core pure/testable.
- js/services/storageService.js: exportAccountRecord / importAccountRecord — get
the on-disk account record and restore it on another device. Import REPLACES
the local record (same-pubkey envelope unlocks with the same signer); cross-
device merge is a follow-up.
- js/services/storageSyncService.js: enable/disable/push/pull under d-tag
"bitvid:storage-connections", with a per-pubkey opt-in flag (off by default).
enable() pushes immediately; disable() wipes the published note.
tests/storage-sync-service.test.mjs: enable-pushes-exported-record, pull-restores
on a fresh device, disable-clears, empty-record-doesn't-publish. Mutation-verified
(skip-import and skip-clear both fail).
