Schedule: On Jellyfin only when the episode itself is there; Aired · not on Jellyfin yet otherwise

For shows AnimeFlow doesn't track, the app now looks the episode up in the
linked Jellyfin (one /Shows/{id}/Episodes per series, 3 min memo; TVDB
number via anilist_map offsets). No linked account: a neutral Aired.
