Current Sent resource model

There is no standalone brand CRUD path in the current v3 API.

• Create a dedicated brand inside POST /v3/profiles using brand and inherit_tcr_brand: false.
• List/create campaigns with GET|POST /v3/profiles/{profileId}/campaigns.
• Update/delete with PUT|DELETE /v3/profiles/{profileId}/campaigns/{campaignId}.
