Template refresh and ditto customization template tools

Visual design
To be up to par with similar documents being communicated to customers elsewhere in our digital world, the document templates (commercial and non-commercial) needs a modernization refresh anno 2022.

Admin customization
All needs are not created equal. So an ability for the non-programmer Admin to easily customize these documents, e.g. through a WYSIWYG editor as today exists for the commercial documents, or in some other way, is needed.  I understand why Invision prioritized the commercial templates with its legal requirements and implications when implementing this. But that is now a while ago, as I understand it.
