Create won deal rows in central premium export sheet

Your won premium deals aren't recorded in the export sheet, which delays billing and monthly reporting. This writes each won deal row to the shared spreadsheet so billing and ops can reconcile same day.

Overview

When premium deals close, they should feed your billing pipeline automatically instead of relying on manual exports. This flow captures each won deal and delivers a row to your export sheet within minutes, enabling billing and revenue teams to reconcile same day.
