fix(dashboard): add VNC WebSocket support in console image build

- Add --file flag to specify Containerfile path in docker buildx
- Build console image from cozystack-ui feat/ui-overhaul branch
- Update console image with VNC fix (includes /k8s proxy location)

New console image includes nginx /k8s location for VNC WebSocket
routing to KubeVirt VMI subresources.
