fix: album shown 2-3x in "In Library" on the artist page

Deezer returns the same album as several variants (single/EP/album/regional/explicit), and
each variant matched the same Navidrome album, so one owned album rendered 2-3 times
("PIXELATED KISSES" x3).

- Web (detail.js): collapse matched entries to one per owned Navidrome album and one per
  not-owned title before classifying (also avoids duplicate track-count fetches).
- Android (categorizeAlbums): distinctBy(collectionId) missed variants with different ids;
  now also skip an owned album already classified.
SW ns-v58.
