test: Add a few basic dialog tests and helpers

This adds basic tests for a few dialogues, showcasing and exercising
the dialog handling code.  Those tests are extremely basic but show
that it is trivial enough to interact with a dialog.

This adds a few helpers to navigate the UI using keyboard events as
well, because it's one of the best methods to verify the actual
interaction works for a user of assistive technologies.
