Use pre-built UI artifacts in Docker build for faster CI

- Make build_docker_database_image depend on ui_build job
- Attach workspace to get pre-built UI from ui_build
- Skip build_admin_ui.sh when UI is already built (check for index.html)
- Applies to both Dockerfile and Dockerfile.database

This gives us faster CI builds (UI builds in parallel with other jobs,
Docker just copies the result) while still including the full UI in the
Docker image.
