Fix ONVIF library integration and improve stream discovery

- Fix ONVIF CallMethod response parsing (returns *http.Response, not structs)
- Add proper XML SOAP envelope parsing for GetProfiles and GetStreamUri
- Use correct types from xsd/onvif package (StreamType, TransportProtocol, ReferenceToken)
- Add strix binary to .gitignore
- Update configuration and API routes
