feat: Minstrel no longer talks to Lidarr: its connection, Delete via Lidarr and the unmonitor options are gone, and the track reports are plain quarantine (M502 #5525)

Migration 0091 drops lidarr_config and renames the quarantine tables, types,
indexes and the history column off the Lidarr name. The Integrations Lidarr
card, the Reports "Delete via Lidarr" action, the merge and remove-track
unmonitor options, the Lidarr audit actions and error codes go, on the
server, web and Android. The README describes acquisition as it is now.
