Send onboarding message when candidate moves stages now

Candidate board moves without messages leave new hires uninformed and interview times unconfirmed. The workflow sends templated messages so coordinators get confirmations same day.

Overview

Manual outreach every time a candidate advances wastes recruiter time and delays confirmations. This flow sends templated candidate messages automatically when a board item moves, so coordinators get confirmations and fill interview or onboarding slots the same day.
