refactor: Use Kustomize for Kubernetes deployment management

- Update kustomization.yaml with newName field for proper image replacement
- Replace individual kubectl apply commands with kustomize build
- Use kustomize edit to dynamically set image tag from CI/CD pipeline
- Simplify deployment to single 'kubectl apply -k' command
- Consolidate verification steps

Benefits:
- Single source of truth for manifest configuration
- Declarative image tag management
- Easier to manage overlays for different environments
- Reduced template duplication
