Subject: Implement Graceful Shutdown for Worker Process

This commit adds robust shutdown handling for the PodcastItLater
worker process. Key improvements include:

- Introduce ShutdownHandler to manage graceful signal handling -
Add checkpoints in job processing to support interruption - Reset
stale jobs stuck in processing state on startup - Modify systemd
service configuration for better process management - Implement
interruptible sleep in main loop - Ensure current job can complete
or be reset during shutdown
