chore(k8s): update kub-deploy workflow and frontoffice deployment configuration

- Modified the kub-deploy.yml to remove cached images using containerd's ctr command, ensuring that both IfNotPresent and Always image pull policies work correctly.
- Updated frontoffice-deployment.yaml to set imagePullPolicy to Always, preventing stale node cache issues with the :latest tag.

These changes improve the deployment process and ensure that the latest images are always used in the staging environment.
