Disable authentication and suppress HTTP warnings

Eliminated all authentication-related warnings in JupyterLab:
- Cookie expiration warnings
- 403 Forbidden errors
- WebSocket authentication failures
- "All authentication is disabled" warning

Show essential startup messages:
- Server URL (http://127.0.0.1:8888/lab)
- Port information
- Extension loading status
