fix: OVA import — scsi bus, boot order, NIC model from OVF, metadata verification

Locally verified against PVE 9.1 with Ubuntu 24.04 cloud OVA:

- Use scsi bus (not sata) for imported disks, matching PVE UI behavior
- Set boot=order=scsi0 for first disk
- Parse NIC ResourceSubType from OVF (VmxNet3, E1000, E1000e, etc.)
  and map to PVE network model instead of hardcoding virtio
- Add MapNicModel() to OvfMetadata with fallback to e1000 for unknown types
- Integration test verifies name, cores, memory, ostype, scsi0, net0, boot

qmpstatus fix (from previous local testing):
- WaitForStatusTransition polls status/current endpoint for qmpstatus
- PVE reports status=running but qmpstatus=paused for suspended VMs
- SDN subnet ID uses zone prefix: {zone}-{ip}-{prefix}
