-- M5b: per-user track quarantines + admin action audit log.
--
-- lidarr_quarantine — one row per (user, track) complaint. PK matches
-- the general_likes pattern. Re-flagging the same track upserts. Deleted
-- on user resolution (un-hide), admin Resolve, or any of the deletes.
--
-- lidarr_quarantine_actions — audit log of admin destructive actions.
-- Snapshot text columns let the log stay readable after the underlying
-- track/album rows are gone.
