build(compose): make devlake image registry configurable

Introduce DEVLAKE_IMAGE_REGISTRY (default: devlake.docker.scarf.sh) for the pre-built devlake-dashboard and devlake-config-ui images in the docker-compose-dev-*.yml files. Operators can override it (e.g. docker.io) to pull directly from Docker Hub and opt out of Scarf download tracking. Default behavior is unchanged.
