Display network information of checkpoints created with Podman

This PR implements support for displaying network information (IP and MAC addresses) from Podman container checkpoints, addressing issue.

Currently, checkpointctl shows IP address information for checkpoints created with CRI-O but not with Podman. For Podman checkpoints, this information is stored in network.status in JSON format.

Implementation:

• Added network.status file parsing functionality
• Added IP and MAC address display to checkpoint show output
• Added test coverage for network information parsing

Testing Results: Before (Original Output) and After (With Network Information output)

The implementation successfully displays:

• Container's IP address
• MAC address
• Maintains existing checkpoint information

Fixes #132
