ui: Expose markCategoryAsRead

Why:
It is nice to have the ability to mark an entire category as read in the
UI. The API already exposes that functionality anyway, so for
consistency reasons, expose it in the UI as well

What:
Add a new handler in the UI to markCategoryAsRead() and amend views and
router to expose the functionality in the UI
