[FIX] website_sale_aplicoop: save-cart-btn listener was never attached

The save-cart-btn event listener was placed after a return statement in
_attachEventListeners(), so it was never executed. Moved it to the correct
location inside the _cartCheckoutListenersAttached block alongside the
other cart/checkout buttons (reload-cart-btn, confirm-order-btn, etc.).
