Code Review

This pull request introduces a new 'Discovery' feed on the home page, which displays trending movies and TV shows from TMDB. It also adds a user preference to toggle this feature. The implementation is solid, with new backend logic to fetch data, frontend changes to display it, and updates to user settings. My review includes suggestions to improve maintainability by refactoring duplicated code, addressing a magic number, and enhancing template conciseness. I've also recommended an adjustment to the caching strategy for better efficiency.

Since discovery it's only implemented for movies and tvshows, I think it should at least be added as a disclaimer in the toggle description.
