[bug\_fix] ImagePullBackOff

Verify the image tag exists, registry credentials are correct \(create or attach an \`imagePullSecrets\`\), and the node has network access to the registry; then re-pull with \`kubectl rollout restart\`.

Journey Context:
You apply a Deployment and the Pod sits in \`ImagePullBackOff\`. \`kubectl describe pod\` reveals \`Failed to pull image "myapp:1.2.3": rpc error: code = NotFound\`. You check Docker Hub and realize the tag was never pushed. After pushing the correct tag the Pod resolves. A second time the error is \`pull access denied\`, which leads you to create a registry Secret, reference it in \`imagePullSecrets\`, and then the image pulls. A third variant occurs in an air-gapped cluster where nodes cannot reach \`registry.k8s.io\`; you mirror the image internally and update the manifest.
