Add course participant to homework monitor and folders

Enrollments arrive without homework records or submission folders, so coordinators can't track assignments or collect files. You get records and folder links ready same day for coordinators.

Overview

If enrollments land without homework context, coordinators spend time recreating records and chasing file links. This flow captures webhook enrollments, enriches them with LMS enrolment data, creates a homework-monitor row and a submission folder, and triggers follow-ups so coordinators have full enrollment context the same day.
