Subject: [PATCH] fix(sonarr): use configured metadata provider for season
 filtering

The Sonarr scanner always filtered seasons against TMDB data, ignoring the configured metadata
provider setting. This caused shows with different season structures between TMDB and TVDB (e.g.
Animaniacs) to be incorrectly marked as fully available, preventing users from requesting missing
seasons.

fix #2466
