Send weekly check-in reminders to inactive coaching clients

When weekly check-in forms go unanswered, coaches lack recent data to adjust client plans. Send Thursday reminders so plans are updated before the next week.

Overview

Missed weekly check-ins leave coaches without the context they need to adjust client plans and can stall progress. This flow finds clients who skipped the form and sends a targeted Thursday reminder so coaches get responses and plans are updated before the next weekly cycle.
