fix: owned albums wrongly shown as "Unvollständig 1/0" on artist page

Deezer's /artist/{id}/albums list omits nb_tracks, so the album total read as 0 and every
owned album (e.g. N!GHT's "Moonlight"/"Yume") was classified as incomplete "1 / 0 Tracks".

- Web (detail.js): resolve the real Deezer track count via the album endpoint for MATCHED
  (owned) albums only — a couple of calls, not the whole discography — and treat an unknown
  total as complete. Genuine partials still work when the true count is known.
- Android (categorizeAlbums): mark partial only when a known total exceeds what you own;
  unknown total counts as complete (never a false "1 / 0").
- CHANGELOG: documented the fix; corrected the Android lyrics known bug (auto-scroll follows
  playback but isn't smooth — it jumps rather than glides). SW ns-v55.
