Follow-ups found while verifying the approve→provision path end to end:
- vmid is now optional: the early required-field check rejected vmid:0
before the cluster VMID guard could auto-assign a free id. Only hostname
is required now; 0 (or a collision) resolves to `pvesh get /cluster/nextid`.
- net0: use ip=dhcp with no gateway when no static IP is given (Proxmox
rejects gw alongside dhcp); only attach gw for a static CIDR.
- bump post-create settle to 10s so a DHCP lease is up before apt runs.
