RBAC permission `clusters.create`. Creates a self-managed kubeadm / k3s cluster on Ankra Cloud servers: a private RFC 1918 network (`network_ip_range`, or an adopted `private_network_id`), a router with NAT for IPv4 egress, a bastion with a public IPv4 and the cluster nodes on the private network only. Plans replace instance types (`bastion_plan`, `control_plane_plan`, `worker_plan`, `etcd_plan`; node groups keep `instance_type`), `template` is the OS image (default debian-13). The preflight runs first and the first failing item is the refusal. kubeadm requires Cilium; the ankra-cloud-ccm is always installed. `bastion_port` is accepted for contract symmetry and ignored: the bastion listens on 22.
