fix: update overlay images to ghcr.io and remove namespace from replica patch

The Kustomize build was failing because overlay images referenced
registry.nxtgauge.com:5000 but base deployments now use ghcr.io.
Also removed namespace from replicas-patch.yaml (namespace already removed from all base deployments)
