Add Debug UI integration and update TestScript interaction logic

- Implement `DebugUi` component for updating and displaying debug information.
- Configure new UI Toolkit assets, including `PanelSettings` and `UIDocument`.
- Update TestScript to support dynamic ForceMode, velocity, and difference tracking with debug UI.
- Minor adjustments to Rigidbody torque and interaction parameters.
