Two visibility fixes so the UI reflects the shelf's real state on the
next scan instead of only after the archive gate:
- Missing items disappear at once: the user-facing filters already hid
archived rows; the same listings now also require missing_scan_count =
0. A deleted or moved-then-not-yet-repointed file vanishes from the
UI immediately, while purge timing stays gated on archived_at plus the
retention window - grace protects data, not visibility. Restored
automatically when the file returns.
- Steam Deck SD-card model for unmounted storage: resolveLibrary stats
each library's folder roots and flags libraries with no live folder
as Offline (LibraryData gains the field, computed at request time so
mounts/unmounts react instantly). The bookshelf shows an empty shelf
plus a 'storage is not connected' notice for an offline selected
library, and both the shared LibrarySwitcher and the bookshelf's
inline select label offline libraries with their true holding counts.
Nothing is marked or purged while offline.
- TotalMediaCount skips offline libraries, so the 'All Books/Libraries'
totals match what is actually visible.
Verified live: renaming uploads/Manga away produced the notice, an
empty shelf, and the offline dropdown label with a corrected total;
renaming it back restored all 38 cards with zero dirty rows.
