- Refactor dirt and stone generation to optimize visible depth and adjust randomization.

- Remove unused `StartWebSocketGateway` function from `websocket_gateway.go`.
- Add security checks to track player-room mapping, enforce valid input, and prevent ID spoofing in `gateway.go`.
- Refactor touch control logic to dynamically position joystick and buttons above gameplay floor.
- Introduce dynamic floor Y-coordinate calculation (`GetFloorYFromHeight`) for better scaling across different screen sizes.
- Adjust rendering logic to align assets, particles, and debug visuals with dynamic screen height transformations.
- Update canvas CSS to support fullscreen scaling without center alignment.
