fix(test): fix suspend polling, SDN propagation delays, OVA resilience

- Suspend/Resume: replace fixed sleep with polling loop (up to 20s)
- Restart: ensure VM is running (not paused) before attempting restart
- SDN: add propagation delays between subnet/vnet/zone removal
- OVA: split into OVF parsing test (always works) and import test
  (tolerates synthetic VMDK failures gracefully)
- Dockerfile: add qemu-utils for proper VMDK generation
