"""Seed the full M&EL domain (idempotent).

Runs the four seeders in dependency order:

1. ``indicators`` — log frame, rows, indicators, targets, data points, RAG
   threshold, outcome/impact assessments, variance snapshots.
2. ``tracking`` — activities, output deliverables, a corrective action.
3. ``reports`` — default ReportTemplate catalogue + a sample published report.
4. ``feedback`` — standing channels, sample submissions, a tracer study,
   course evaluations.

Seeding a published report fires ``mel_report_published`` which the feedback
receiver listens to, so ReportReview channels are created automatically.
