fix: make dialog the right height and make it scroll if it's smaller (#7103)

I've marked the project creation dialog as "compact", so that it's only
as tall as it needs to be.

However, by default, compact forms don't scroll because they have
overflow set to hidden. This is a problem on very short windows. To get
around this, I've set overflow to unset on compact forms.

I've also removed `min-height: 0` which has some weird side effects on
the centered dialog. Instead, I'm setting `min-height` to `unset` if
it's compact.

This task also uncovered some inconsistencies and some borders that only
show up sometimes, so I've removed them too.
