Aleksei Sviridkin c841c70866 feat(operator): replicate operator wildcard certificate to tenant namespaces
The operator-provided wildcard MVP serves the root tenant only: the root
ingress controller and Gateway read a TLS Secret from their own namespace.
Child tenants run their own ingress controller / Gateway in a separate,
default-deny namespace and cannot read that Secret cross-namespace.

Add a controller that mirrors the operator wildcard Secret into every
tenant namespace that owns a TLS termination point (its
namespace.cozystack.io/ingress or .../gateway label equals its own name).
The source is identified by name from the platform values channel
(_cluster.wildcard-secret-name) with no extra operator input; replicas
carry a managed-by label and refresh on rotation. An individual replica is
removed when its namespace stops terminating TLS; every replica is torn
down only on an explicit disable (clearing wildcard-secret-name). A missing
or mistyped source, or a transiently-absent values channel, keeps existing
replicas, so tenant TLS never drops on a transient gap. The controller's
Secret cache is scoped to managed replicas and the values channel, not
every cluster Secret. Only the platform controller's ServiceAccount gains
Secret writes — no tenant RBAC is widened, and every consumer reads only
its own-namespace copy.
