fix(zoominfo): default required outputFields on enrich; parse nested API error object

- ZoomInfo enrich endpoints require outputFields; send a curated default set when omitted so requests don't fail
- extractZoomInfoError now reads the GTM REST nested error object ({error:{code,message}}) instead of dropping it to a generic HTTP message
