ClusterIssuer solver referenced IngressClass "nginx" which does not
exist on cozystack clusters — real classes are named after tenant
namespaces (e.g. tenant-root). Cert issuance only worked because every
requesting Ingress overrode the ClusterIssuer via the legacy
acme.cert-manager.io/http01-ingress-class annotation.
Switch both sides to the modern cert-manager API (available since
cert-manager 1.12; cozystack ships 1.19.3):
- ClusterIssuer: http01.ingress.ingressClassName, value parameterized
from _cluster.expose-ingress (default "tenant-root")
- Ingress annotation: http01-ingress-ingressclassname
These must migrate together — mixing ingressClassName (ClusterIssuer)
with the old http01-ingress-class annotation triggers cert-manager's
"fields ingressClassName and class cannot be set at the same time"
validation and breaks issuance.
