Enhance product price display and styling

- Added `flex-wrap: wrap;` to the product display container in custom.scss for better layout management.
- Introduced a new CSS class `.gm_omniprice` to ensure price elements are displayed as block and take full width.
- Moved the hook `{hook h='displayProductPriceBlock' product=$product type="after_price"}` to the product-prices template for improved modularity and flexibility in price display.
- Removed the redundant hook call from the product template to maintain a clean structure.
