+-- Fix puntual: column "cnt" does not exist en jsonb_agg(row ORDER BY cnt DESC).
+-- El alias cnt vive en el subquery interno; el nivel externo del jsonb_agg solo
+-- ve `row`. Solución (Opción B): exponer cnt en el SELECT externo para que
+-- jsonb_agg(row ORDER BY cnt DESC) pueda referenciarlo en ese nivel.
+-- Solo se tocan estas dos funciones; las otras 9 rpc_me_* no se modifican.
