fix: resumen - group terceros by cedula, prioritize success over warning

GROUP BY COALESCE(factura, cedula) fixes terceros (factura=NULL)
collapsing into one row — each paciente now gets its own row.
CASE WHEN in estado_final explicitly prioritizes success > warning > error
instead of relying on alphabetical MAX which returned warning over success.
