-- Adds how many portions a recipe yields as written (`Recipe.portions`) —
-- the planning recipe picker now pre-fills its own "how many portions?"
-- step from this (see `RecipePickerDialog`), closing the gap noted on
-- `PlanningItem.portions`'s own migration ("no such default exists ... on
-- `Recipe` either"). Backfills any pre-existing row with 4 portions (a
-- reasonable default recipe yield) via a transient DEFAULT, then drops it
-- so it isn't implicitly reused for new inserts going forward — same
-- pattern as `20260819064721_planning_item_portions`.
