## Summary
- Adds `group: gateway.networking.k8s.io` and `kind: Gateway` to all `parentRefs` entries
- Adds `group: ""`, `kind: Service`, and `weight: 1` to all `backendRefs` entries
- Affects 9 HTTPRoute files across artifactapi, cattle-system, consul, kanidm, litellm, paperclip, puppet, and vault
## Why
ArgoCD diffs the desired manifest against the live Kubernetes object. The Gateway API controller defaults these fields when creating/updating objects, so the live state always has them — causing persistent OutOfSync for every HTTPRoute. Same root cause as #153 (certificateRefs).
## Test plan
- [ ] All affected ArgoCD applications show Synced after merge
Reviewed-on: #162
Add port 80 HTTP listener and redirect HTTPRoute to artifactapi,
cattle-system (rancher), litellm, paperclip, and puppetboard — restoring
the redirect behaviour that existed on the previous nginx/traefik Ingress
resources.

## Summary
- Replace `Ingress` (nginx) with `Gateway` + `HTTPRoute` using `traefik-internal` GatewayClass
- TLS terminated at the Gateway listener; cert-manager provisions the certificate via `vault-issuer`
- external-dns annotations moved to the Gateway
## Test plan
- [ ] ArgoCD syncs the cattle-system app cleanly
- [ ] cert-manager issues the `rancher-tls` certificate
- [ ] external-dns creates the DNS record
- [ ] `https://rancher.k8s.syd1.au.unkin.net` is reachable
