Draw background images all the way to the bottom of the screen in edge-to-edge mode

See https://github.com/Helium314/HeliBoard/pull/1461#issuecomment-2811722558:

It should be possible to create a wrapper view that is edge-to-edge for the background image, and have just the keyboard itself inset. I can try to do that in a separate RB if you'd like.

If you want to try, you're welcome to do so. But this is more an idea for an improvement than a necessary fix, so I'd say it's lower priority. In case you want to try: my first idea would be using the InputView as wrapper, or maybe the linear layout in main_keyboard_frame (as the background image should be set on this).

I can't really tell whether this would be desired behavior, but I thought drawing the image under the navigation bar makes sense. Not sure though whether Android can correctly set the button colors to have acceptable contrast. Maybe someone who wants or doesn't want this change can comment?
