Add co-op agent details to closed transaction record

Closed transactions missing co-op agent contact details stall post-closing outreach and reporting. This adds agent name, email and phone to the transaction record for immediate follow-up.

Overview

Closed transactions that arrive without co-op agent details create last-minute manual work and missed outreach. This flow enriches the transaction record with agent name, email and phone so coordinators can complete follow-up and reporting the same day. It reduces manual lookups and keeps post-closing tasks on schedule.
