Refator: Refactor timer implementation across multiple classes to use System.Timers.Timer instead of CTimer for improved consistency and performance.

- Updated RelayControlledShade to utilize Timer for output pulsing.
- Refactored MockVC to replace CTimer with Timer for call status simulation.
- Modified VideoCodecBase to enhance documentation and improve feedback handling.
- Removed obsolete IHasCamerasMessenger and updated related classes to use IHasCamerasWithControls.
- Adjusted PressAndHoldHandler to implement Timer for button hold actions.
- Enhanced logging throughout MobileControl and RoomBridges for better debugging and information tracking.
- Cleaned up unnecessary comments and improved exception handling in various classes.
