feat(ecosystem): update PM2 configuration for control plane and web server

- Renamed the control process to `jflow-control` and updated the script path to `control.js`. - Introduced a new `jflow-web` process for the production UI, serving on port 8500. - Enhanced environment variable handling for both processes, ensuring proper port assignments. - Updated README to reflect new process architecture and usage instructions for starting the application.
