Total Revenue dashboard widget alignment + bottom corners are knackered

[mattstein]

Description

This Commerce Total Revenue widget displaying actual sales from my book, How to Infuriate Coworkers with Tedious UI Issues, has two minor visual glitches:

1. Its right alignment is slightly off:
   
2. Its bottom corners are a little muddy:
   

This is consistent in each of the browsers I tested.

I fully expect this has to do with ApexCharts, and would of course expect flush right alignment and clean corners like those other widgets.
