Remove all SPICE WebSocket-related code due to frontend dependency issues
with spice-html5 library (missing RSAKey/BigInteger implementations).
Changes:
- Remove start_spice_websocket_console() from BaseNode
- Remove SPICE WebSocket endpoints from QEMU and Docker compute APIs
- Remove SPICE WebSocket proxy endpoint from controller API
- Remove WebSocket subprotocol handling from authentication layers
- Remove SPICE documentation
The SPICE console type remains functional for direct connections,
but WebSocket proxy support has been removed.

Add WebSocket-based console support for SPICE protocol, enabling
browser-based graphical console access with enhanced features
like clipboard sharing, USB redirection, and audio streaming.
Changes:
- Add start_spice_websocket_console() method in BaseNode for SPICE
WebSocket to TCP bridging with bidirectional binary forwarding
- Add /console/spice WebSocket endpoints in QEMU and Docker compute APIs
- Add /console/spice WebSocket proxy endpoint in controller API
- Add comprehensive API documentation in docs/features/
Supported console types:
- spice: Basic SPICE protocol support
- spice+agent: SPICE with spice-vdagent for enhanced features
Architecture:
- Browser WebSocket → Controller (JWT + RBAC) → Compute (Basic Auth)
- No external websockify processes required
- Consistent with existing VNC WebSocket implementation
Add VNC console WebSocket endpoints for Docker and QEMU nodes:
- Add /console/vnc WebSocket endpoint to compute API (Docker & QEMU)
- Add /console/vnc WebSocket endpoint to controller API
- Implement start_vnc_websocket_console() in BaseNode
- Forward VNC WebSocket traffic between controller and compute layers
The implementation provides bidirectional WebSocket to TCP forwarding
for VNC protocol (RFB) connections, allowing browser-based VNC console
access to containers and VMs.
