Account settings refactor

Closes https://github.com/natebenson/vyllage/issues/803. Closes https://github.com/natebenson/vyllage/issues/943.

In the end I only moved some things a bit and added a bunch of tests, I'm not sure if it's even worth trying to simplify things more.

@tarex, @nelonoel , any ideas?

It would be nice if this was more digestible into smaller PRs. Try to break it up in the future.
