ArtistResource has no top-level `monitor`. Lidarr reads the choice from
AddOptions (AddArtistOptions, a MonitoringOptions), so the "all"/"future"
we sent there was dropped on deserialisation. AddOptions.Monitor stayed
Unknown, and AlbumMonitoredService.SetAlbumMonitoredStatus returns early
on Unknown. The request's monitoring was never applied.
Send monitor and monitored inside addOptions with searchForMissingAlbums,
the shape Lidarr's getNewArtist.js posts, and set monitorNewItems "all"
explicitly: both choices mean new releases are watched.

Lidarr's POST /api/v1/album validates `artist` as a nested resource
(AlbumController: RuleFor(s => s.Artist).NotNull()), so the flat payload
we sent was refused with "'Artist' must not be empty" every time. The
album add has never worked against a real Lidarr; approved album and
track requests sat in the reconciler retrying every 5 minutes.
AddAlbum now does what Lidarr's own add-album UI does (getNewAlbum /
getNewArtist): look the album up by MBID (album/lookup?term=lidarr:<mbid>),
then POST that resource back with monitored + searchForNewAlbum. When
Lidarr doesn't have the artist yet, the nested artist gets the request's
quality/metadata profile and root folder, monitors this album only
(monitor "none" + albumsToMonitor, which AlbumMonitoredService prefers)
and no future releases. An artist Lidarr already has is left as it is.
An MBID Lidarr's metadata doesn't know is ErrNotFound with no POST.
