Links a data field to an impact area, attributed to the caller, drops the cached classification views of that area and its ancestors, and answers the link as stored. 409 `impact_area_to_datafield_link_exists` when the pair is already linked. `dataFieldId` and `impactAreaId` are required: legacy also stored a link with no data field or with an empty impact area as NULL.
