platos: paywall inmediato al llegar al limite y orden alfabetico

- attemptAddDish/attemptCreateDish: el limite gratuito se comprueba en el
  tap de anadir plato (DishListView y los 3 puntos de Home) y muestra el
  DishLimitModal -> paywall directamente; antes solo se comprobaba al
  guardar el formulario y el usuario podia rellenarlo entero para nada
- DishLimitModal compartido (era private de DishFormView) y
  PaywallPresentation promovido a PremiumView.swift; DishListView usa
  sheet(item:) tambien para el banner (source dish_counter vs dish_limit)
- Boton en la toolbar de Mis Platos que alterna orden alfabetico
  (persistido en dish_list_alphabetical_sort); borrado por swipe corregido
  para usar la lista mostrada
