Increase the color contrast for elements using the color orange on the commerce inbox

working on it!!

Please review!!

@anirudhsingh19 The warning color is part of our global brand palette, so we shouldn’t change it globally just to meet contrast for this one element. And why change the font weight?
@rkoller We can keep the dot orange, since it’s decorative and not the only indicator (we have bolder text).
For accessibility, we can change the unread text color to black.

@majmunbog I have reverted the global value of warning color. And yes, I agree that we could leave the dots the same. @rkoller Do you have any suggestions?
