feat: filter out genres in discovery, default user settings

[Sn1perdog]

Description

Using TheMovieDB's without_genres query parameter, we are able to filter out chosen genres out of our search for movies and TV Shows.
Added user settings for both categories, as these have different genres, which automatically gets applied every time the user goes to the Discover pages and when viewing the Popular X.

If a user adds a genre to the (Exclude) Genre, it gets removed from the other one and vice versa.

• [nitpick] The variable userDefaultfilterGenres breaks camelCase consistency—consider renaming it to userDefaultFilterGenres.

  const userDefaultfilterGenres =
