## Problem
GatewayClasses were `Unknown` even after controllerName was fixed. The `kubernetesGateway` `labelSelector` applies to all watched resources, including GatewayClasses themselves. Since neither GatewayClass had a `traefik.io/instance` label, both Traefik instances filtered them out and never accepted them.
## Fix
- `gatewayclass-internal.yaml`: add `traefik.io/instance: internal`
- `gatewayclass-external.yaml`: add `traefik.io/instance: external`
## Test plan
- [ ] `kubectl get gatewayclass` shows both as `Accepted: True`
