feat: implement dynamic sort parameter for AniList watchlist

Add configurable sort functionality to AniList watchlist system:

- Add aniListSort writable store to GlobalVariablesAndHelperFunctions
- Update Pagination component to subscribe to and use dynamic sort parameter
- Refactor CheckIfAniListLoggedInAndLoadWatchList to use sort from store
- Remove hardcoded MediaListSort.UpdatedTimeDesc in favor of configurable sort
- Improve code formatting with arrow functions and consistent spacing
- Add sort parameter to all GetAniListUserWatchingList calls

This allows users to customize their watchlist sorting preference instead of being limited to the default 'updated time descending' sort order.
