## What
Now that the ActorTemplate CRD has been deleted and its resources moved
to the substrate gRPC API and the control-plane store (created/managed
with `kubectl-ate`, persisted in PostgreSQL), several documents still
describe ActorTemplate as a Kubernetes CRD, or describe namespace/RBAC
relationships that no longer exist. This sweeps the docs for those stale
references.
Fixes#368 (docs side).
