Refactor CSS and JavaScript for product comparison and wishlist functionality

- Updated `dr_materac.scss` to hide the compare/wishlist button by default.
- Enhanced JavaScript in `detail1526395446.tpl` to safely add an event listener for the opinions section link, ensuring it only attaches if the element exists.
- Cleaned up the `product-add-to-cart.tpl` by uncommenting the compare/wishlist button section for better visibility in the UI.
