Remove WebSocket handshake debug messages unless --debug is enabled

- Modified websocket_handshake() function to accept debug parameter
- Updated all debug messages in websocket_handshake to only print when debug=1
- Updated all callers of websocket_handshake() to pass debug flag
- Fixed compilation warnings and ensured clean build
- WebSocket handshake messages now only appear with --debug flag
