feat(media): import movies and series into Notion

[MaximilianMauroner]

Movies and series need manual metadata entry, and the current issue does not choose a dependable source or define the Notion mapping.

Proposed change

Choose one maintained movie and television API. Add search, match preview, and import for both media types.

Acceptance criteria

• Search distinguishes movies from series.
• Imports include title, artwork, synopsis, genres, release date, and rating when available.
• Series can store season and episode counts.
• Repeated imports do not create duplicates.

@MaximilianMauroner I would decide between Movie Database (up to 1000 requests per day) and IMDB (up to 100 requests per day).

• Check what information will be send by both API's
