[IMP] website: make cover_properties a mixin field

Next commit will add new cover properties entries for the bg color.
Still, we want a default `bg-primary` class. Instead of addind 3 new default
value in existing cover_property fields, the chance is taken to make a mixin
out of that field to avoid code duplication.
