chore: enhance data source configuration and mock data handling

- Added support for mock data mode in the frontend by introducing a new environment variable in the Dockerfile and workflow configuration.
- Updated the settings page to conditionally display options based on the availability of mock data, improving user experience.
- Refactored data source logic to include a check for mock data availability, ensuring proper mode handling in the application.
