3. Remove an item from the cart:

   cart_service.remove_item(item_id=1)
   

4. Increment item quantity:

   cart_service.increment_item_quantity(item_id=1)
   

5. Decrement item quantity:

   cart_service.decrement_item_quantity(item_id=1)
   

6. Apply a discount to the cart:

   cart_service.apply_discount(discount_percentage=10)
   

7. Clear the entire cart:
