Enhance Jenkinsfile for E2E testing diagnostics

- Added a 10-second sleep before the E2E testing begins to allow Vite/Uvicorn to start up, improving log visibility for troubleshooting.
- Included commands to output the status of the Docker containers and the last 40 lines of logs for both frontend and backend services, aiding in debugging during the E2E testing process.
- Adjusted the timeout for waiting on the frontend from 300 seconds to 180 seconds, streamlining the waiting logic.
