Add coexistence checks to all enqueue methods to prevent loading both React and Grid.js assets simultaneously. Changes: - ReactAdmin.php: Only enqueue React assets when ?react=1 - Init.php: Skip Grid.js when React active on admin pages - Form.php, Coupon.php, Access.php: Restore classic assets when ?react=0 - Customer.php, Product.php, License.php: Add coexistence checks Now the toggle between Classic and React versions works correctly.
