refactor: move shared servarr types into servarr_models

SystemStatus was declared three times, byte for byte identically, in
radarr_models, sonarr_models, and lidarr_models. MetadataProfile and the
Lidarr release download body were each declared in a single servarr module
despite having nothing servarr specific about them: MetadataProfile is an
id and name pair structurally identical to QualityProfile, which already
lives in servarr_models, and a download body of a guid plus an indexer id
is the generic form of that request.

Move all three into servarr_models, preserving that file's alphabetical
ordering, and drop the prefix from LidarrReleaseDownloadBody now that it is
no longer owned by one servarr.

RadarrReleaseDownloadBody and SonarrReleaseDownloadBody deliberately stay
where they are. Radarr's carries a movie id and Sonarr's carries optional
series, episode, and season fields, so the three types are not
interchangeable and only the Lidarr shape is the common one.

Behavior is unchanged. Every remaining edit is an import path update or the
rename at a call site.
