# setup_metabase_volume
# ---------------------
# Copia registry.db al contenedor Docker de Metabase.
# Compone: assert_file_exists + assert_command_exists +
#          assert_docker_container_running + docker_cp_file
#
# USO:
#   ./setup_metabase_volume.sh [REGISTRY_DB_PATH] [CONTAINER_NAME] [DEST_PATH]
#
# ARGUMENTOS (opcionales, con defaults):
#   REGISTRY_DB_PATH  Ruta local al registry.db
#                     Default: <raiz_del_registry>/registry.db
#   CONTAINER_NAME    Nombre del contenedor Docker de Metabase
#                     Default: metabase
#   DEST_PATH         Ruta destino dentro del contenedor
#                     Default: /registry.db
