[FIX] website_sale_aplicoop: prevent grid destruction on event listener attachment

Browse source 
The _attachEventListeners() function was cloning the products-grid element
without its children (cloneNode(false)) to remove duplicate event listeners.
This destroyed all loaded products every time the function was called.

Solution: Use a flag (_delegationListenersAttached) to prevent adding
duplicate event listeners instead of cloning and replacing the grid node.

This fixes the issue where products would disappear ~1-2 seconds after
page load.
