Firewall Status Page Should Use non-Red/Green Color Scheme

To support Red/Green color-blind users, we should use a different color scheme: a small number of users (1 - 3%, depending on source) have the most common type of color blindness and can't differentiate red and green. It's difficult to differentiate the statuses if you can't see the colors.

We should resolve this by switching color pallets (blue / yellow, blue / white+black, etc.) or adding additional non-color indicators, like bold or italic formatting to different statuses.
