Add actions "Unbury Deck," "Rebuild Filtered Deck," and "Empty Filtered Deck" to the "Deck Browser" tab

[dmantula]

This is a feature request, not a bug report.

I rely heavily on filtered decks. My filtered decks are sorted according to my learning priorities, and my daily routine involves the following steps:

1. I empty each filtered deck.
2. I rebuild the first deck in my list and study it.
3. Upon completing the first deck, I rebuild and study the next one, and so on.

It would be incredibly useful to perform these actions—"Rebuild Filtered Deck" and "Empty Filtered Deck"—directly from the Deck Browser using assigned buttons on my joystick.

Additionally, I've reviewed the Anki's code and it seems that the "Unbury Deck" action is adjacent to the "Rebuild" and "Empty" actions. I think adding this actions would be useful for users who study in multiple sessions throughout the day.

Thank you for considering this request!
