Add real-time simulation configuration endpoint and update frontend components

- Introduced a new API endpoint for retrieving real-time simulation configuration, allowing users to view progress and metadata during simulation generation.
- Updated frontend API service to include the new real-time configuration method.
- Enhanced Step2EnvSetup.vue to support real-time polling for configuration updates, improving user experience during simulation setup.
- Revised display logic to show detailed configuration summaries and orchestration content, enriching the simulation setup process.
