feat(clone): real disk-copy progress, owner assignment and DB registration

- _do_clone_sync now tails the PVE clone task log and maps the disk
  transfer percentage to deploy progress 50→95% instead of a static 70%.
- Add owner_id to CloneRequest; admins may assign the clone to another
  user (mirrors LXC deploy). Register the cloned instance via
  save_vm_instance so it has an owner and is visible to limited users.
