apply_group_inherited_visuals(GraphData*, db_path) recorre los nodos Group del grafo y, para cada uno, consulta los type_ref distintos de sus hijos (entities con group_id apuntando al Group). Si todos comparten un solo tipo, reasigna el type_id del Group al type_id de ese tipo y fija shape_override = SHAPE_SQUARE para preservar el cuadrado distintivo. Heterogeneo o sin hijos: el Group conserva su visual generico (slate + ti-stack-2). Se invoca desde main.cpp y reload_graph antes de apply_group_filter para que la reasignacion sobreviva al compactado del array.
