HoneyandClaude Opus 4.8 bdf2867bdd fix(backend): album downloads search by per-track artist, not the album artist
downloadAlbumTracks passed each track's artistName as `artist` but no `rawArtist`,
so in ytdlp.js the YTM/YouTube search query and the channel filter used
`mainArtist = albumArtist || artist` — always the album-artist blob. On mixed-artist
soundtracks that matched nothing: e.g. TWICE's "Strategy" and MeloMance's "Love,
Maybe" were searched as "KPop Demon Hunters Cast, HUNTR/X & Saja Boys <title>" with
`channel ~= KPop`, and failed with "Nicht eindeutig gefunden".

Pass rawArtist = track.artistName so the search + channel filter use the actual
performer ("TWICE Strategy", channel ~= TWICE). The album_artist tag still comes from
`albumArtist`, so album grouping is unchanged.
