Stamp checklist record with submission time for projects

Build checklist submissions often lack timestamps, leaving step order unclear and handoffs delayed. It stamps submission time to the matching project checklist so managers have completion context same day.

Overview

When build checklist submissions lack timestamps, coordination stalls and managers spend time reconciling status manually. This flow stamps each submission into the central checklist and updates the matching project record within minutes, so operations and project managers get reliable completion context the same day.
