Re-add filtering / hiding to the Calendar view

I used the calendar view a lot to see which recently aired episodes I haven’t collected yet. That’s my main use of the trakt web side, which doesn’t seem possible in any view currently with V3.

The V3 calendar view itself is quite useless currently because it’s not even possible to drop things I’m not watching, so it’s cluttered with a lot of noise, drowning the things I actually want to see.

I’m quite sad to see the current state of the trakt website 🥲 . I hope you can get the thing to a usable state before loosing too many users…
