Rework for use in Flutter demo platform image

Changes:
- Converted to portrait orientation.
- Application enumeration and launching+activation enabled via use
  of applaunchd gRPC API and agl-shell protocol platform channel
  plugin in the embedder.
- Previous dashboard, hvac, media, etc. pages disabled. Some of
  the code has been kept for potential reuse.
- Clock widget tweaked to fit in portrait mode navigation bar, and
  take text color argument.
- Bluetooth, wifi, and phone signal icons mocked up in navigation
  bar.

Known issues:
- The bottom panel area is static at present, support for popping
  up a volume control slider like the Qt demo is planned as an
  addition.
- The path to implementing connection and signal strength indications
  is currently a bit hazy, it is possible that flutter-dbus might
  be the simplest stopgap.
- State management has been kept basic, as there are a couple of
  places where using provider or riverpod seems like perhaps an
  overcomplication.  This will be reviewed when KUKSA.val support is
  integrated for the volume slider.
- Some of the layout sizing is a bit ad hoc, and it is not clear if
  the previous layout helper class is actually worth keeping or not.
  This should be reviewed when time permits.
