[Thunear]

Create a new section on the color page of the themebuilder that shows all the status colors. Needs to solve the following:

• When the user has brand colors that might conflict with the status colors and wants to compare them.
• When a user has their own status colors and wants to compare them

• Invalidate color names that we use internally in theme generation #3132
