huecos sin planificar y exclusiones en la lista de la compra

- MealSlot.isSkipped: opcion "No planificar esta comida" en el picker de
  hueco vacio — cuenta como resuelto (semana completa, notificaciones,
  stats) y el autocompletado lo respeta; vista gris con guion, tap para
  desmarcar; viaja en undo, snapshot KV (junto con isEatingOut, que
  faltaba en el payload) y exports (— en imagen, omitido en texto)
- ShoppingItem.isDismissed: "Ya lo tengo" por ingrediente (swipe
  izquierdo) y "Ya esta hecho" por plato entero (boton en la cabecera de
  su seccion); van a la seccion "Ya en casa" con restauracion de un tap,
  y quedan fuera del export de texto. No se borran porque reconcile los
  recrearia
- Esquema CloudKit Development: CD_isSkipped, CD_isDismissed y el record
  type CD_ShoppingItem entero, que no existia — la lista de la compra no
  estaba sincronizando entre dispositivos (mismo bug que photoData)
