Graceful Shutdown with SIGTERM Handling

Scenario:

You have a container image myapp:grace built from /home/interview/Dockerfile that runs an application requiring cleanup on shutdown. When you run docker stop, the container is killed after the 10-second timeout instead of shutting down gracefully because the application doesn't properly handle the SIGTERM signal.

Task:

Fix the application script and Dockerfile to properly handle SIGTERM signals, implement cleanup logic, and ensure the container exits gracefully within 20 seconds when docker stop is executed.
