Filtering Bugs + OPDS Want To Read (#2210)

* Fixed Summary not allowing an empty field, as it should allow that.

* Cleaned up some localization wording and put a todo for a bug with library filtering not working.

* Added Want to Read to OPDS stream

* Implemented the ability to disable adding filter rows for bookmarks page which only supports one filter type.

* Fixed the library filtering code

* Fixed a bunch of titles across the app. Fixed about system page not showing data quick enough.

* Hide API key by default and show a button to unhide. Fixed a styling issue with input group buttons.

* Fixed a hack to support zh_Hans language code to work for things like pt-br as well.

* Fixed transloco not supporting same language scheme as Weblate, but somehow needs all languages.

* Fixed the rating on series detail not being inline with other sections
