reglas: plato fijo por dia y comida (ej. tortilla los viernes de cena)

- Dish.fixedDayOfWeek/fixedMealType (opcionales, aditivos para CloudKit)
- Toggle + pickers de dia/comida en el formulario de plato
- AutocompleteEngine: pre-pasada que asigna los platos fijos a su hueco
  antes del bucle MRV, de modo que cuentan para el resto de reglas
- Evento analytics dish_fixed_slot_set; strings en 6 idiomas
