Handle SIGTERM signals to gracefully shut down the server without killing in-flight document generation requests.

Requirements:

In server startup file, add process.on('SIGTERM', ...) handler
On SIGTERM:
- Stop accepting new connections (server.close())
- Log 'Received SIGTERM, draining N in-flight requests'
- Track in-flight requests with a counter incremented on request start, decremented on finish
- Wait up to 30 seconds for in-flight requests to complete
- If timeout expires, force exit with code 1
- If all requests complete, exit with code 0
Add middleware to track in-flight request count (increment on request, decrement on response finish)
Also handle SIGINT for local development

Acceptance criteria:

SIGTERM during active request: request completes before shutdown
SIGTERM with no active requests: immediate clean shutdown
30s timeout prevents indefinite hanging
Exit code 0 for clean, 1 for forced
