Schedule: "on Jellyfin" for shows AnimeFlow doesn't track, AniList episode numbers

From real use: a show on Jellyfin read "not in AnimeFlow". AnimeFlow's
new GET /library lists every Jellyfin series with AniList ids per TVDB
season; matchSchedule uses it for untracked shows (status inLibrary,
Put it up, no Request) and to fill jellyfinSeriesId. A failing or
missing /library never fails the schedule. Episodes may carry
anilist_episode (split cours, absolute numbering), matched first.
