spectator view sharing other session objects

[skim0119]

TL;DR

Added spectator and arm camera modes with new UI controls and session binding logic.

What changed?

• Added new session modes: "spectator" and "arm_camera" with corresponding join buttons in the UI
• Created session_bindings.js module with functions to handle arm binding logic for different camera modes
• Implemented arm_camera_controller.js for controlling camera position based on arm states with smooth interpolation
• Added spectator_avatar_manager.js to manage spectator avatar selection and rendering
• Enhanced the main app with better code organization through comments and extracted session binding logic
• Added arm camera panel with user and arm selection dropdowns

How to test?

1. Load the VR client interface
2. Click "Join as Spectator" to enter spectator mode and observe automatic arm following
3. Click "Join Arm Camera" to enter arm camera mode
4. In arm camera mode, use the new panel to select different users and arms
5. Verify smooth camera transitions when switching between arms
6. Test that head arms are properly filtered from selection options

Why make this change?

This change introduces new viewing modes for users who want to observe sessions without actively participating. The spectator mode automatically follows active users, while the arm camera mode provides precise control over which arm to follow with smooth camera movements. This enhances the collaborative experience by allowing observers and improves the overall usability of the VR system.
