The Gateway API admission server defaults certificateRefs[].group to ""
when it is omitted. ArgoCD diffed the desired state (no group field) against
the live state (group: "") and flagged every gateway as out of sync.
Fix: explicitly set group: "" in all certificateRefs entries so the
rendered manifest matches the API server's canonical form exactly.
Affected: artifactapi, cattle-system, consul, litellm, paperclip,
puppet (puppetboard + puppetdb), vault.
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
