Without atomic: true, Helm install can mark the release as deployed
even if some resources (like DataStore) fail to create. This leads to
silent failures where etcd StatefulSet is running but DataStore CR
is missing, preventing any Kubernetes cluster creation in the tenant.
With atomic: true, Helm will fail the install if any resource fails
to create, triggering proper retry via install.remediation.retries.
Fixes partial resource creation issue described in #2412.
