Add new account admin prospect to onboarding list

Flagged account creation requests often miss admin contacts, delaying welcome outreach. Add those admins to the onboarding list automatically so campaign managers can begin outreach same day.

Overview

If admin contacts flagged for onboarding don't get enrolled, welcome outreach stalls and conversion drops. This flow automatically turns those flagged records into prospects and enrolls them in the onboarding campaign, enabling campaign managers to start targeted outreach same day.
