Closes #12628

Description

Noticed that in dark mode badge view text color is to dark. Since the background color of badg view is black I set the text color to plain white.

Testing instructions

• Open orders
• Add product(s) to the order
• Check that the number if badge is readable
• Test it in both light and dark mode

Thanks for fixing! Maybe it's worth noting this in the release notes?

super nit: maybe we can mention "dark mode" as a "fix" since this change doesn't affect the light mode
