fix(postgres-operator): block HelmRelease Ready until the cnpg webhook actually serves
The cnpg admission webhook's controller pod passes readinessProbe as soon
as the local HTTPS server binds to :9443. The HelmRelease marks itself
Ready right after that via helm install --wait. But the Service
cnpg-webhook-service needs its EndpointSlice populated and the data plane
(kube-proxy / cilium) programmed before kube-apiserver can reach the
webhook through the Service ClusterIP. That gap is short but not zero,
and any HelmRelease that depends on postgres-operator (cozy-keycloak,
tenant Postgres apps) can fire its own install inside the window and hit

  Internal error occurred: failed calling webhook "mcluster.cnpg.io":
  failed to call webhook: Post "https://cnpg-webhook-service.cozy-postgres-operator.svc:443/...":
  dial tcp <svc-ip>:443: connect: connection refused

which fails the install of the downstream release. Seen on cozystack/cozystack#2470
E2E run 24862782568.

Add a post-install,post-upgrade Helm hook Job that blocks the release
from reporting Ready until the webhook answers /readyz through the
apiserver service proxy. Apiserver proxy routes the call over the same
Service IP → EndpointSlice → pod path the admission webhook uses, so
once it responds, the webhook admission path is also working.

RBAC is minimal: a dedicated ServiceAccount with a ClusterRole that only
grants get on services/proxy scoped to https:cnpg-webhook-service:webhook-server.
The Job times out after 120s with 60 attempts at 2s intervals — longer
than any data-plane programming delay seen on E2E, but bounded.
