fix(ui): fix permissions dialog rendering on small windows (#2093)

Andrey Nering created 1 week ago

* Ensure the viewport content is at least 3 cells tall, to always be able
  to render at least 1 line of content + 1 top and 1 bottom margin.
* Render in fullscreen as soon as we don't have enough space to render
  buttons without wrapping.
