Update lead records when team flags messages for follow-up

You lose context when team reactions flag prospects but your lead sheet isn't updated, causing routing delays. Leads get accurate qualification timestamps and same-day routing for follow-up.

Overview

When your team flags a message about a prospect, that signal needs to make it into the lead sheet immediately or follow-up slips. This flow captures flag-based qualification and writes timestamps so marketing ops and campaign managers can act same day and keep attribution intact.
