🐛(backend) ensure SIP dispatch rule instead of creating it

The roomkit can now create a SIP dispatch rule before the LiveKit
webhook that used to trigger this creation is fired. In practice,
when the roomkit connects to the room, it also triggers the
webhook, leading to a duplicated dispatch rule.

Switch from "create dispatch rule" to "ensure dispatch rule exists"
semantics, so subsequent calls are idempotent and no duplicate rule
is created.

 Monitor Tilt’s progress at [http://localhost:10350/](http://localhost:10350/). After Tilt actions finish, you can access the app at [https://meet.127.0.0.1.nip.io/](https://meet.127.0.0.1.nip.io/).
+
+### Alternative: OrbStack's built-in Kubernetes (macOS)
+
+If you use [OrbStack](https://orbstack.dev/) on macOS, you can run the stack on its built-in Kubernetes cluster instead of kind. It uses noticeably less RAM (no nested kubeadm node container) and no local registry is needed: OrbStack's cluster shares the Docker image store, so Tilt uses images directly without pushing.
+
+Enable Kubernetes in OrbStack (Settings > Kubernetes), then:
+
+```shellscript
+$ make build-k8s-cluster-orbstack
+```
+
+This installs ingress-nginx (exposed by OrbStack on `127.0.0.1:80/443`), the mkcert TLS certificates, and the CoreDNS rewrite for `*.127.0.0.1.nip.io`, then you start Tilt as usual:
+
+```shellscript
+$ make start-tilt-keycloak
+```
+
+Notes:
+- Ports 80/443 must be free: delete the kind cluster first if you used it (`kind delete cluster --name suite`).
+- If you "Reset Kubernetes" in OrbStack, re-run `make build-k8s-cluster-orbstack`.
+- kind remains the reference setup (matches CI and lets you pin the Kubernetes version).
