Implement a "Simplified View" option that allows users to hide two of the four available recording channels, presenting a simplified two-channel interface.
User Story:
As a user I occasionally utilise all four recording channels, I want the ability to toggle a simplified view that displays only two channels to focus on my primary inputs and reduce visual clutter when I'm not using all 4 channels.
  1. Add a "Simplified View" toggle in the UI
  2. When activated, the UI displays only two video channels.
  3. Users can select which two active channels to display in the simplified view.
  4. The full four-channel view remains accessible and can be easily restored.
  5. The system remembers the user's preference for subsequent sessions.
