* show discount on cart line items (no styling)
* style line item discount badge + use correct colors for prices
* show full price inline on mobile
* move all responsive tweaks for cart prices to explicit breakpoints
* add nowrap to FormattedMoneyAmount so prices don't ever wrap
* fix misaligned full price on mobile when prices are large (edge case):
- if price strings are long, the full price stacks above line total
- previous right-margin on full price showed prices misaligned
* allow client code to add class(es) to FormattedMonetaryAmount
* add nowrap so discount badge doesn't wrap
* remove unnecessary span from discount badge +
+ more explicit `display` style for different price column elements
