refactor: use Navigation3, pass rust types to screens and add navigation viewmodel

[ovitrif]

note: Now that all rust types from our libraries are serializable, we should be able to do a great refactoring where we're just passing the type.

Also Navigation3 is finally stable, so this means we should soon refactor all navigation logic, which is very bad, but we didn't have any better choice given Compose's navigation was too poorly designed.

I will plan this refactoring.
