List the forwards of a campaign, with the contact that forwarded it and the address it was forwarded to. This is the v3 equivalent of the v1 campaign_report_forward_list action.

The underlying query takes no sort parameter, so no orders parameter is accepted, and the response carries no meta.total.

Requires the Campaigns feature and access to the campaign; a campaign the user cannot see is reported as 404 so the endpoint does not disclose which campaign ids exist.
