Fold all incremental schema changes into the baseline migration so that
a fresh database only needs to run one file:
- recipe_source enum now includes 'menu'
- recipe_products/recipe_product_translations renamed to
recipe_ingredients/recipe_ingredient_translations; product_id → ingredient_id
- menu_items.meal_type CHECK expanded to all 6 types
(breakfast, second_breakfast, lunch, afternoon_snack, dinner, snack)
