feat: use pty proxy for rendering tui popups without clearing the terminal (#3234)

It feels much, much nicer this way. This has also been asked for pretty
consistently since we made inline rendering the default. Now we can have
everything :)

Maintains a shadow vt100 renderer so that we can restore the terminal
state upon popup close. This happens on a background thread, so our
impact on terminal performance should still be super minimal, if
anything

## Checks
- [ ] I am happy for maintainers to push small adjustments to this PR,
to speed up the review cycle
- [ ] I have checked that there are no existing pull requests for the
same thing
