Add functional test for physical product handling option CSRF
This test closes the coverage gap that allowed the CSRF token bug to reach production. The handling option form requires CSRF protection but no test exercised this code path because all existing functional tests use digital products. New test verifies: - Physical product handling option form renders correctly - CSRF token is present and accepted by the view - All handling options work (pickup, delivery, local/intl shipping) - Form submission succeeds without 400 Bad CSRF Token error Closes test coverage gap for make_post_sell/views/cart.py:404
