Send templated email on lead stage change and notify owner

Lead records lose outreach context when stages change, leaving reps without contact details. It sends a templated message and logs a contact timestamp so owners and reps have confirmation same day.

Overview

When a lead moves stages, outreach can be inconsistent and reps lack proof of contact. This flow sends the right, stage-specific message and logs a contact timestamp automatically, giving owners and reps confirmation within minutes so follow-up happens on schedule.
