+ * F4 elimina dos campos heredados de la planificación original de Inspecciones:
+ * - title: la Inspección se identifica por su código autogenerado.
+ * - planned_end_at: la planificación sólo define la fecha/hora prevista de inicio.
+ *
+ * Se conserva un índice sobre planned_start_at porque sigue siendo un criterio de
+ * orden y filtro operativo. El rollback reconstruye la forma original de D1.
