Saves push silently as before, but if the relay copy is NEWER than the one this
device last pushed (another device changed it), the user is now asked to confirm
before overwriting — preventing a silent multi-device clobber. No nag on normal
saves.
- js/services/settingsSyncFlags.js: track per-pubkey+kind last-pushed created_at
(getSyncPushedAt/setSyncPushedAt).
- js/services/syncConflict.js: pushWithConflictCheck — peek remote created_at
(list-only, no decrypt), compare to last push, call confirmOverwrite only on a
real conflict, then push strictly-newer than remote so the replace wins.
- storage/walletSyncService push()/enable() route through it and accept a
confirmOverwrite callback.
- ProfileStorage/WalletController supply confirmOverwrite (window.confirm) and
surface a "kept the newer copy" status when the user declines.
tests/sync-conflict.test.mjs: no-remote→silent, newer→prompt(+decline blocks
push), confirm→strictly-newer push, older→no prompt. Mutation-verified
(ignoring the decline fails). Service-test twins gained exists().

Wires the storage-credential sync (6f7f4196) into the profile Storage pane.
UI (components/profile-modal.html): a "Cross-device sync" card shown only when
storage is unlocked — an opt-in toggle ("Sync these settings to my Nostr account
(encrypted)"), a "Restore from my Nostr account" button, the public-relay /
key-compromise warning copy, and a status line.
Controller (ProfileStorageController):
- toggle on -> storageSyncService.enable() (encrypt + publish), with rollback +
message if nothing is stored yet; toggle off -> disable() (wipe the note)
- restore -> pull() + re-render the pane so the restored connection shows
- after a successful Save, re-push the synced copy when sync is enabled
Also routes the core's relay READ through the subscription manager (injected
listEvents) instead of pool.list, satisfying lint:pool-access for the new file;
the facade supplies it via nostrClient.getSubscriptionManager().list.
