Wire Requests approval into Radarr/Sonarr with live download status

Admin can now Approve a pending request as Movie or TV, which looks up
the title via Radarr/Sonarr's own lookup API, adds the best match with
search-on-add enabled, and tracks the resulting radarr_id/sonarr_id on
the request. A live status line (searching/queued/downloading/downloaded,
polled every 15s) shows next to each approved request.
