- Resolver: capture banner_url + separate avatar (by thumbnail id), keeping
per-video duration/views for the detail hero.
- query_youtube_wishlist reshaped to the EXACT TV-nebula shape: channel = show,
upload YEAR = season (newest first), video = episode (newest=ep1 within a
year), carrying source='youtube' + youtube_id + per-video source_id. Surrogate
int returned as tmdb_id so the nebula's int keying just works.
- New API: GET /youtube/channel/<id> (full channel detail — meta + deeper
uploads + following + per-video wished flags) and POST /youtube/wishlist/add
(per-video wish). DB: youtube_video_wish_state, remove_one_video_from_wishlist.
- Tests updated for the nebula shape + banner + detail endpoints. 82 DB + 69
api/youtube tests green.
