Splits the previous LikedIdsController into two:
- likedIdsProvider — StreamProvider reading from cached_likes via
drift watch(). Reactive: SyncController writes propagate
automatically. Empty + online triggers REST cold-cache fallback
that populates cached_likes via insertOrIgnore (sync may have
already written some rows).
- likesControllerProvider (new) — exposes toggle(LikeKind, id).
Optimistic: writes drift first (UI updates instantly via the
watch stream), then REST. Rolls back drift on REST failure.
Two consumer updates: like_button.dart + track_actions_sheet.dart
switch from likedIdsProvider.notifier.toggle to
likesControllerProvider.toggle.
