[iris] Fix dev cluster restart ghcr.io auth failure (#4089)

The controller restart command builds Docker images and pushes them to
ghcr.io/marin-community/, but both dev restart workflows were missing
packages:write permission and the docker/login-action step, causing
pushes to fail with "unauthenticated". Adds both to
iris-dev-restart.yaml
and iris-coreweave-dev-restart.yaml, matching docker-images.yaml.
