Fallback display languages

[rasko-dev]

Description

It would be nice to allow selecting multiple display languages in order, so when a show or movie that doesn't have a translation on TMDB for your most preferred language, it could fall back to other options.
For example when I have selected Norwegian as a display language, and I search Squid Game, I get the original Korean title and episodes named "Episode 1", "Episode 2" etc. Although when in the search field, the english title Squid Game is listed. It's only when I click it the Korean title appears.

This would also help me getting proper Norwegian translations, because TMDB uses several forms of Norwegian "no-NO" "nb-NO" and "nn-NO". This is honestly unnessecary on their part, because it causes some movies to be translated using one, while others are translated under the other even though it's the same language. This feature would allow me to just choose all of these, (although the others would have to be added to jellyseer because right now only Norwegian Bokmål (nb-NO) is listed).

Desired Behavior

Allow choosing multiple display languages, in order of most preferred, and if any episodes, descriptions, titles etc do not have a translation in your preferred language it will use your next preferred language.

I think this would be really complicated to implement. It would require a huge refactor of the application to handle all the translations that are returned by TMDB, since TMDB doesn't support this.

For the different forms of Norwegian, I think it's worth contacting TMDB on their forum to ask if it could be simplified.
