Create a new visual config

Creates a new visual config and corresponding custom template with validation rules applied.
Important Notes:

• rendered_oid fields 4 (description) and 8 (steward) are required in the payload as default fields.
• Validation ensures:
  • layout_otype is a valid object type.
  • All rendered_oid fields are registered in the application.
  • If the layout_otype is glossary_term or glossary_v3 , there’s an additional top level property: collection_type_id, which refers to the Document Hub ID.
