Add the storage behind the archive-instead-of-delete lifecycle:
- media_items.missing_scan_count (INT, default 0) and archived_at
(TIMESTAMPTZ, partial index), both as idempotent ADD COLUMN IF NOT
EXISTS backfills for existing installs.
- MarkMediaItemMissing / ArchiveMediaItem / ClearMediaItemArchive plus
PurgeExpiredArchivedMediaItems (retention cutoff) and
PurgeAllArchivedMediaItems (manual bulk), with CountArchivedMediaItems
for the admin UI.
- Archived items are hidden from every user-facing listing:
ListMediaItems, ListMediaItemsByLibrary, ListMediaItemsSorted,
SearchMediaItems, SearchMediaItemsUnified, the next_books CTE, the
library media counts, and the search autocomplete value lists. Detail
lookups by id/path/sha are intentionally unfiltered, and a dedicated
ListMediaItemsByLibraryIncludingArchived feeds the scanner so the
lifecycle pass can see and restore archived rows.
