fix(radarr): model the download status as a DownloadStatus enum

Radarr was the only tree still holding DownloadRecord.status as a bare
String and comparing it against literals. It now carries its own
DownloadStatus enum, shaped exactly like the Sonarr, Lidarr and Readarr
copies, and is guarded with from_json_or_default so an unrecognised
status degrades to Unknown instead of failing the whole queue fetch.

The row-style decorator and get_movie_status compare against the enum
variants. The status cell is never rendered in the Radarr tree, so no
snapshot changes; the CLI JSON output is unchanged for every real value
since the enum serializes to the same camelCase strings.
