feat: add TV show trailer downloads, episode trailers, and movie/TV trailer separation

- Download trailers for TV shows from TMDB with separate sources and an
  independent max-count cap (0 disables a category)
- Play trailers before TV episodes via IIntroProvider, limited to the first
  episode a user watches each day
- Tag TV show trailers in their NFO so movies only get movie trailers and
  episodes only get TV show trailers

 changelog:
-  - Add trailer selection filters — genre match, age rating ceiling, and avoid-repeats
-    cycle; genre and rating are written to each fake-movie NFO at download time from
-    TMDB so Jellyfin can use them for filtering; filters fall back to random when no
-    match is found
+  - Add TV show trailer downloads — separate TMDB sources (Airing Today, On The Air,
+    Popular, Top Rated) and a "Max TV show trailers per run" cap independent from
+    movies; set either cap to 0 to skip that category entirely
+  - Add trailers before TV episodes via IIntroProvider — only the first episode a
+    user watches each day gets trailers, picked using the show's genre/rating for
+    filtering
+  - Movie and TV trailers are now kept separate — movies only ever get movie
+    trailers and episodes only ever get TV show trailers, via a tag written to each
+    trailer's NFO at download time
