feat: mark recipe as cooked (multi-cook history + backdate) and enable auto-deduct pantry on cook (v0.75.0)

Adds a general-purpose "mark cooked" dialog for any recipe (not just batch-cook dishes), with a date picker for backdating and a pantry-deduct checkbox defaulted on. Also flips the previously dead-in-the-UI deductFromPantry flag to true for the existing batch-cook and meal-planner cook actions.
