2.0: beta feedback — edit dish from shopping list + dish photos in planner

- Shopping list: dishes under "No ingredients yet" now open the dish editor on
  tap (pencil affordance); list reconciles on dismiss. This was a dead end on
  devices without Apple Intelligence (no Generate button, e.g. iPhone 14).
- Planner: dish photo as a scrimmed card background in the week calendar,
  behind a new Settings toggle (settings_show_dish_photos, default on). New
  optional AppSettings.showDishPhotosInPlanner (CloudKit/migration safe).
- FilledSlotView: inlines the meal-card chrome to support the photo layer.
- Toggle localized in all 6 languages.
