Fix all cook/deduction endpoints: use canonical alias matching everywhere

Replaced SQL LIKE pattern matching with isIngredientInInventory() in:
- POST /api/recipes/cook (direct cook from Recipes page)
- PUT /api/calendar/:id/cook (cook from Calendar)
- POST /api/cook/check-opened (opened items check)

This ensures renamed inventory items and generic_name matches work
correctly during deduction, same as recipe ingredient display.
