fix(nests): respect navigation bar insets in NestActionBar

The bottom action bar in NestFullScreen was rendering under Android's
gesture navigation area in edge-to-edge mode, leaving the leave / talk
/ react buttons partially obscured. Apply BottomAppBarDefaults
windowInsets to the surface so it pads above the system navigation.
