debug: add logging to diagnose PMG backup detection issue #359

Added console.log statements to understand why PMG backups with VMID=0
are still showing as LXC in v4.14.0. This will help identify:
- What data type vmid is (string vs number)
- What backup type is being sent
- Whether the checks are being triggered
