yonluandClaude Opus 5 dcc40b1781 feat(albums): get an album's track total from the files, not the catalog
The album page asked MusicBrainz how many tracks an album has, because
the only total it had was the length of the tracklist it was already
showing — a tautology for a library copy. The denominator was on disk
all along: metadata has read the "5/12" totals off every file since
forever and discarded them. They persist to
release_group_recordings.total_tracks now, and a complete, MBID-matched
album makes no catalog call at all.

Around that:

- AlbumReleasesFailed, so a slow browse is no longer reported as a
  failed one. The page inferred failure from a 12s deadline, against a
  browse queued behind up to eight prefetches on a 1 req/s limiter.
- Tracks not in the library are dimmed in place rather than the owned
  ones carrying a green tick, which is also what let the "loading
  catalog" banner go.
- A partly-owned album draws the release, not the part, so the missing
  tracks are visible and Play can say "9 of 12" truthfully.
- The version dropdown appears only when tracklists actually differ,
  and the version you own is marked by name instead of being replaced
  by a synthetic "Your Library" entry.
- A merged cluster shows the running order the most releases agree on,
  not whichever pressing the browse returned first — which is what made
  a correctly matched album claim it was unlinked from MusicBrainz.

Also carries in-progress work from earlier sessions that shared these
files: the queue source link, autotag mixed-bag grouping, the mix
feature and its schema, and the config general page.

Committed with --no-verify: every pre-commit check was run by hand and
passed, but bindings-check refuses to run while frontend/wailsjs is
dirty and counts *staged* as dirty, so it cannot pass on any commit
that updates the bindings. Verified separately by regenerating and
diffing against the staged content.
