[bug\_fix] ImagePullBackOff

Run \`kubectl describe pod -n \` and read the Events. If the event says \`manifest unknown\` / \`not found\`, correct the image name/tag or push the missing tag to the registry. If it says \`unauthorized\` for a private registry, create a docker-registry Secret with \`kubectl create secret docker-registry ...\` and attach it via \`imagePullSecrets\` on the Pod or ServiceAccount. If it times out, verify node egress and DNS resolution to the registry.

Journey Context:
A deployment was updated by CI to use \`myapp:v1.2.3\`, but the new pods stayed in \`ImagePullBackOff\`. \`kubectl describe pod\` showed \`Back-off pulling image "myapp:v1.2.3"\` with a \`NotFound\` manifest error. The pipeline had built and pushed \`latest\` but had skipped the tagged push for the release commit. After pushing \`v1.2.3\` to the registry, the kubelet pulled the image and the pods started. In another case the error was \`unauthorized\` because the cluster was pulling from a private registry and the namespace's default ServiceAccount had no \`imagePullSecrets\`; creating the registry secret and patching the ServiceAccount fixed it.
