## Summary - Adds `group: gateway.networking.k8s.io` and `kind: Gateway` to `parentRefs` - Adds `group: ""`, `kind: Service`, and `weight: 1` to `backendRefs` ## Why The Gateway API controller defaults these fields when creating/updating TLSRoute objects, so the live state always has them. ArgoCD diffs desired vs live by string comparison, causing the `kanidm` TLSRoute to show permanent OutOfSync. Same root cause as #162 (HTTPRoutes). Reviewed-on: #165
