Owner

Add a graceful shutdown handler to the Express server for production deployment readiness. Required by #908 (Dockerfile).

Implementation:

Create a shutdown() function that: logs 'Shutting down...', calls server.close() to stop accepting new connections, closes the database connection pool (pool.end()), then calls process.exit(0).
Add a 10-second force-exit timeout: setTimeout(() => process.exit(1), 10000) in case connections don't drain.
Register process.on('SIGTERM', shutdown) and process.on('SIGINT', shutdown).

Without this, Docker container restarts will leak database connections and may cause pool exhaustion under load.

Acceptance: Sending SIGTERM to the running server triggers logged shutdown sequence, closes DB pool, exits with code 0 within 10 seconds.
