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.
