Remove QML rotation container causing partial repaint on linuxfb

The rotation transform on the main container was causing touch/rendering
issues on embedded displays with linuxfb backend:
- Touch to wake showed console window instead of app
- Swiping/touching only rendered the touched portion

Removed:
- rotationContainer with 180° rotation
- InputPanel rotation
- Custom rotated error dialog (Pi 5 workaround)
