State badge color

[KameDomotics]

Hi, I would like to propose this new feature.

• Customize the color of the status badge
• Armed: GREEN (now)
• Disarmed: GRAY (now)

Actually you can customize the text and other parameters, but not the color of the status badge.

I didn't find the way to change these badge colors in the theme .yaml file (Google Dark Theme).
