fix(quarantine): use name-based group key across batches/sources

Browse source 
Source-specific IDs (Spotify id, Qobuz id, URI) break sibling detection
when the same song is imported from different playlists or sources, since
each batch produces a different id: key. Siblings from a second batch were
never recognised and stayed in quarantine after approving the first.

Drop id:/uri: fallbacks; keep only ISRC (truly universal) and nm:artist|track
(stable across all sources). This correctly groups all quarantine entries for
the same intended target regardless of which batch or source produced them.
