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
## Notes
The original Ingress had nginx-specific annotations (`proxy-body-size: 10g`, `proxy-read-timeout: 600`) which are not portable to Gateway API. These can be re-introduced via a Traefik `Middleware` CRD if needed.
## Test plan
- [ ] ArgoCD syncs the app cleanly
- [ ] cert-manager issues the `artifactapi-tls` certificate
- [ ] external-dns creates the DNS record
- [ ] `https://artifactapi.k8s.syd1.au.unkin.net` is reachable

Split monolithic remotes.yaml into per-type-package files under
resources/conf.d/ to align with artifactapi v2.7.1 directory loading.
Updated schema: virtuals/locals use dedicated top-level keys, type field
removed. Added helm remotes for all kustomize helmCharts repos and
OCI patterns to docker remotes. CONFIG_PATH now points to the directory.
