feat: video rips and stray copies handle themselves (M498 #5439)

- The resolver also merges cross-release and mismatch groups where Lidarr
  maps exactly one copy: the others fulfil nothing, so removing them opens no
  hole (D-a rule 1). That covers a rip beside the clean copy on another
  release and a wrong-file import Lidarr holds unmapped. With two or more
  mapped copies each fulfils its own release and nothing is removed.
- A track whose file name carries a video-rip marker is held back from radio
  and the system mixes (tracks.source_verdict, migration 0077). It still plays
  when chosen. A renamed file is released; the operator's "fine" sticks.
- Suspect sources shows what was done to each track, with "This one is fine"
  and "Hold back again" (PUT /api/admin/library/suspect-sources/{id}).
- The Liked list prefers a copy that is not held back.

Replacing a rip that has no clean copy is left for the operator to decide.
