[bug\_fix] MountVolume.SetUp failed for volume: secret/configmap/config path not found

The kubelet cannot mount a volume because the referenced Secret, ConfigMap, or projected volume source does not exist, or the optional flag is false. Create the missing object, or set \`optional: true\` if the workload can tolerate its absence. For ConfigMap/Secret volume mounts, the object must exist in the same namespace as the pod before the pod is scheduled to the node.

Journey Context:
You deploy a StatefulSet that mounts a TLS Secret as a volume. The pod is stuck \`ContainerCreating\`. \`kubectl describe pod\` shows \`MountVolume.SetUp failed for volume "tls-certs" : secret "api-tls" not found\`. You check and see the Secret was created in namespace \`prod\` but the StatefulSet is in namespace \`api\`. Kubernetes Secrets are namespace-scoped, so the kubelet on the node cannot find it. You either move the Secret to the \`api\` namespace or re-create it there, and the volume mounts successfully. The error looks like a storage issue but is actually a namespace scoping mistake.
