Website editors can now access Unsplash images through a new integration, making it easier to find and use high-quality visuals. The change also adds the necessary settings and permissions so website designers can use the feature when the related enterprise module is installed.

This commit:
1. Adds settings to install the new `web_unsplash` enterprise module.
   See counterpart commit on enterprise for details.
2. Export `ImageWidget` and `update_control_panel` to be able to override them.

This update adds onboarding guidance to help businesses connect bank accounts for invoicing and complete key setup steps before selling online. It makes the invoicing and eCommerce dashboards more helpful by surfacing configuration tasks and banners in one place.
