feat(mobile): review remote-trashed assets before syncing deletions

Adds a "Review remote deletions" mode for trash-sync: when the server
marks a remote asset as deleted, the local copy is queued for user
review before being moved to the device trash. The existing auto-sync
mode (Android-only, requires MANAGE_MEDIA) keeps the silent-mirror
behavior. iOS gets the review surface only — auto-sync is hidden
because PhotoKit prompts on every batch, defeating the silent intent.

State lives on a single trash_sync_entity table keyed by local_asset_id
with three decisions (pendingReview / kept / appTrashed) and two
trigger sources (remoteSync / localUser). Both review-mode decisions
and auto-mode transitions are single-row column updates on the same
table, so the cross-repo atomicity bug from the original draft cannot
recur structurally.

Other shape choices:
- UI subscribes to watchPendingReviewCount() to surface a review-badge
  notification — no event-stream needed.
- recheckRemoteTrashCandidates() closes the durability gap from acked
  assetDeleteV1 events arriving before the local was hashed.
- Auto-restore is gated on TrashSyncMode.autoSync; review mode never
  fires OS-level trash or restore on its own.
- Predicates query backup-album selection dynamically via existsQuery,
  so assets in multiple selected albums aren't dropped during dedup.
- getAppTrashedRemotelyRestored joins trashed_local_asset_entity for
  album reconciliation (the asset leaves local_album_asset_entity after
  auto-trash but stays in the OS-trash mirror).
- Bucket queries use SQL GROUP BY date instead of Dart-side reduce;
  shared predicate subquery between bucket and asset paths.
