- Added CORS allowed origins in config.compose.yaml to enable cross-origin requests from the web service.
- Updated docker-compose.yml to include a new web service with build context and port mapping for local development.
- Enhanced gateway.go to support additional HTTP methods in CORS responses.
- Updated README.md to document the new web service and its configuration requirements.
