This PR updates the supervisord configuration to ensure services restart reliably.
The Problem
When supervisord stops a service, it defaults to sending the stop signal only to the main parent process.
Any child processes (like a web server, background worker, etc.) would be orphaned, keep running, and hold onto network ports. This caused subsequent restarts to fail with an EADDRINUSE ("address already in use") error.
The Solution
This change adds two flags to the [program:app] configuration:
stopasgroup=true: Tells supervisord to send the stop signal to the entire process group, including all child processes.killasgroup=true: As a fallback, ensures the entire group is killed if the graceful stop fails.This guarantees that all processes are properly terminated, freeing up ports and allowing supervisord to restart services cleanly. This fix is application-agnostic and improves reliability for any service that spawns child processes.
