- Updated Dockerfile to build and embed the SvelteKit Web UI directly into the gateway image, eliminating the need for a separate web service. - Modified .dockerignore to exclude unnecessary directories related to the web service. - Adjusted config.compose.yaml to remove CORS settings for the web service, as the UI now shares the same origin as the API. - Enhanced README.md to reflect the new single-port architecture for accessing both the Web UI and API. - Removed the standalone web Dockerfile and updated related documentation for local development and build processes.
