/**
 * Consolidation migration: upsert all email and internal notification
 * templates from the source-of-truth files.
 *
 * This migration is idempotent — safe to run on both fresh and existing
 * databases. It ensures every category, subtype, and template variant
 * is present and up-to-date.
 *
 * After this migration, template content lives in:
 *   server/migrations/utils/templates/email/   (email templates)
 *   server/migrations/utils/templates/internal/ (internal notification templates)
 *
 * Future template changes only need to:
 *   1. Edit the source file
 *   2. Write a small migration that re-imports and upserts
