2.0: dish editor gains photo picker and ingredients section

- PhotosPicker with downscaling (1024pt max, JPEG 0.8) before storing in
  photoData; change/remove actions.
- Ingredients: editable line list (add/edit/remove) + on-device "Generate"
  from the dish name (hidden when Foundation Models unavailable; paywall
  after the free generation quota, source=ingredient_generation).
- DishViewModel: drafts ingredients/photo, cleans empty lines on save.
- Localized in all 6 languages.
