Four more domain-eng modules out of `api/subsonic.ts`:
- `subsonicPlaylists.ts` — `getPlaylists`/`getPlaylist`/`createPlaylist`
/`updatePlaylist`/`updatePlaylistMeta`/`uploadPlaylistCoverArt`/
`uploadArtistImage`/`deletePlaylist`. The two upload helpers use
the Tauri-side CORS bypass (`upload_playlist_cover` /
`upload_artist_image`).
- `subsonicPlayQueue.ts` — `getPlayQueue`/`savePlayQueue`.
- `subsonicRadio.ts` — Internet Radio CRUD (4 fns), Tauri-side cover
art ops (3 fns), RadioBrowser search/top + `fetchUrlBytes`.
- `subsonicStatistics.ts` — `fetchStatisticsLibraryAggregates`/
`fetchStatisticsOverview`/`fetchStatisticsFormatSample` with their
three per-server-folder caches and the `statisticsPageCacheKey`
helper. `STATS_CACHE_TTL` renamed from the misleadingly-shared
`RATING_CACHE_TTL` constant.
Also: drop ~20 now-unused type/value imports from `subsonic.ts`, trim
three orphan jsdoc comments left behind by earlier slices, fix four
`vi.mock` targets (`queueSync`, `playerStore.persistence`) plus the
dynamic `await import('../api/subsonic')` calls in `ContextMenu.tsx`
to point at the new module paths.
Pure code-move. subsonic.ts: 561 → 144 LOC (−417). What's left:
ping/pingWithCredentials/probeInstantMix/scheduleInstantMixProbe +
internal `apiWithCredentials`/`restBaseFromUrl`.
