Trying to Add WASD Camera Control (Still Broken) + Car Switching and UI Improvement. Mobile cam 0.2 Tier 2

Car Switching Support
The camera now automatically follows the car you're currently using. It updates properly when you switch cars and resets values to avoid bugs.

Better Camera Handling
Camera mode is now more compatible. It saves and restores the previous view when turning off. Visual adjustments only apply to the current car.

Improved Interface
It shows the current car number and driver name, and gives a visual cue when you switch cars.
