/**
 * CloudXRUI.tsx - CloudXR User Interface Component
 *
 * This component renders the in-VR user interface for the CloudXR application using
 * React Three UIKit. It provides:
 * - CloudXR branding and title display
 * - Server connection information and status display
 * - Interactive control buttons (Start Teleop, Reset Teleop, Disconnect)
 * - Responsive button layout with hover effects
 * - Integration with parent component event handlers
 * - Configurable position and rotation in world space for flexible UI placement
 *
 * The UI is positioned in 3D space and designed for VR/AR interaction with
 * visual feedback and clear button labeling. All interactions are passed
 * back to the parent component through callback props.
