fix(ui): remove subtotal lines

[dstaley]

Description

This PR removes the subtotal lines from checkout as currently the subtotal will always equal the grand total. In the future when we support taxes (which are added after the subtotal) we can restore these lines, but as they are now they're just redundant information.
