Simplify home view and drop motion detection

- Top nav tabs (Home/Media/Cameras/Settings) replace the right-side button cluster
- Home view now shows calendar 90% / todo 10% vertically; lights, locks,
  alarm, thermostats removed from the dashboard since the photo frame now
  owns the idle space and the nav covers the remaining sections
- Motion detection deleted: the go2rtc-based Kitchen_Panel poll was only
  there to wake the screen before idle timeout, which photo-frame exit on
  touch replaces
