/**
 * Dev helper: run the @tria-plc/iamapi-common TypeORM migrations against the shared `iam` schema.
 *
 * The package ships its migration CLI assuming you run it from inside the package repo (it needs
 * the package's devDeps). As a consumer we instead drive the shipped (compiled) migrations with the
 * passenger app's own installed TypeORM.
 *
 * Reads the same DATABASE_* env vars as the app's IAM DataSource (see config/iam-database.config.ts).
 * Run via:  pnpm --filter @edr/passenger-api iam:migrate
 * (the npm script loads .env with `node --env-file`).
 *
 * NOTE: in production the central IAM team owns/runs these migrations — this helper is for local dev.
