Switch deployment pipeline from GitLab Agent kubectl to FluxCD image automation. CI now only builds and pushes tagged images to Forgejo registry; FluxCD detects new tags and updates the deployment manifest. Fix Ecto.MultipleResultsError on /dashboard when a device has multiple Preseem access point records by using limit(1) instead of Repo.get_by.
