Ingredients aren't attributable to individual batch dishes (they're one
merged/shared list for the whole prep session, unlike steps which have
`appliesTo`) — the cooked route's pantry-deduction block was unconditionally
skipped whenever batchDishId was set, so pantry was never touched for any
batch-cook recipe.
Deducts once, on the first dish marked cooked for that recipe+user (checked
via prior cookingHistory rows) — matches the fridge/freezer-day design
intent of "cook the batch once, eat dishes over several days" rather than
deducting (or trying to deduct) per individual dish.
Verified locally: first dish cooked deducted the full recipe's ingredients
from pantry; second dish cooked did not double-deduct.
