Update loop_interval in Tracker class and handle timeout while processing shipments

- Update loop_interval to 60 seconds
- Add loop_timeout to Tracker class with a value of 30 seconds
- Wrap process_shipment calls in asyncio.wait_for with timeout set to loop_timeout value
- Add try-except block to handle TimeoutError and log a warning message
- Code changes aim to improve the handling of long-running shipments processing with a timeout mechanism in place
