Simplify pantry UX and persist grocery check state server-side

- Remove quantity, unit, expiry, and category fields from pantry form; auto-detect category via keyword map
- Persist grocery item checked/unchecked state in DB via PATCH /api/grocery/{id}/check-item
- Fix unchecking: previously bailed early and never removed the checked class
- Fix NOT NULL constraint on ingredients.unit by defaulting to empty string
