feat(hypervisor): generalize create_vm_from_cloud_init interface to support arbitrary NIC configs

- Replace fixed mgmt/capture dual-NIC parameters with generic NICConfigDict list
- Add optional disk_resize_gb parameter for post-clone disk expansion
- Update docstrings to reflect generic NIC approach (primary NIC concept)
- Add NICConfigDict TypedDict supporting access VLAN, trunk VLAN, and DHCP flags
