As per the new designs, the quantity picker should be moved below the product metadata, and the product subtotals should appear below the product name.
* Move line item total to top of grid on mobile/medium/small
* Remove CSS for trash icon that is no longer used.
* Remove link style colour override from product name and make total bold

* Always disable link to product in OrderSummaryItem
* Add single price below product name in OrderSummaryItem

* Remove line height from product names on order summary
* Add more margin to the bottom of the product metadata div
