Force dark or light color scheme

On the ADR 0006 we discuted a way to force color scheme (dark or light) to ensure widget color scheme outside of django-admin. The two cases bellow is tested using UI regression tests.

Light theme

To enforce light widget, use .iuw-light class:

<div class="iuw-light">
  {{ form }}
</div>

Dark theme

To enforce dark widget, use .iuw-dark class:

<div class="iuw-dark">
  {{ form }}
</div>
