The single authentik Gateway kept cert-manager.io annotations (vault-issuer,
common-name identity.k8s.syd1.au.unkin.net) while its public identity.unkin.net
https listener referenced the reflector-managed wildcard-unkin-net-tls. The
cert-manager gateway-shim mints a Certificate per distinct listener secretName
from Gateway-level annotations, so it would create a competing vault-issuer
Certificate for wildcard-unkin-net-tls and fight the emberstack reflector over
that secret.
Split into two Gateways mirroring the cheeztv/fafflix convention:
- authentik (public): identity.unkin.net listeners on wildcard-unkin-net-tls,
no cert-manager annotations, external-dns publishes identity.unkin.net.
- authentik-internal: identity.k8s.syd1.au.unkin.net listeners on authentik-tls
with the vault-issuer cert-manager annotations, external-dns publishes the
cluster host. Both target 198.18.200.4.
Update HTTPRoutes to attach each hostname's redirect + app route to the
matching gateway's http/https sections.
