ui: customizable tabs per column view

This reduces the number of choices the user needs to make. Some of these
filters were redundant anyways. This also saves memory.

Universe: Notes
Notificaitons: Notes & Replies
Everything else: Notes, Notes & Replies

Changelog-Changed: Simplified tab selections on some columns
Fixes: https://github.com/damus-io/notedeck/issues/517
