Flow and playlist songs that aren't in the Library got skipped in Music Assistant. They reported parent: flow:<id> (or shared:<id>), MA looks that up with getAlbum, and getAlbum only knows albums, so it answered "not found" and MA dropped the track. Fixes #1745.

Songs now only point at an album that exists:

• Playlist songs that match a Library track keep that track's real album as parent, the same as getSong returns for that id.
• Playlist songs outside the Library leave out parent and albumId. The Subsonic spec makes parent optional, and MA plays a track with no album id.
• Library songs with no album no longer get the made-up album:unknown parent.

Proof: two new assertions in the Subsonic integration tests fail on main and pass here; pnpm run check, pnpm test, and pnpm run test:integration pass.

Reviewed with sol-loop: 1 round with gpt-6.1-sol. Sol verdict: approved
