cmd/{containerboot,k8s-operator},kube/kubetypes: kube Ingress L7 proxies only advertise HTTPS endpoint when ready (#14171)

cmd/containerboot,kube/kubetypes,cmd/k8s-operator: detect if Ingress is created in a tailnet that has no HTTPS

This attempts to make Kubernetes Operator L7 Ingress setup failures more explicit:
- the Ingress resource now only advertises HTTPS endpoint via status.ingress.loadBalancer.hostname when/if the proxy has succesfully loaded serve config
- the proxy attempts to catch cases where HTTPS is disabled for the tailnet and logs a warning
