Admin-only handler. Calls tracks.RemoveTrack with the unmonitor flag parsed from the query string. ErrNotFound -> 404; everything else unexpected -> 500. Lidarr-side failures during unmonitor flow as lidarr_unmonitor_failed: true in the success envelope (non-fatal — the file + DB delete already completed).
