/**
 * Provides `IamBaselineSeeder`. The app calls `run()` itself — usually from
 * `onApplicationBootstrap`, after whatever seeder creates the organization the
 * super admin attaches to.
 *
 *     IamSeedModule.forRoot({
 *       superAdmin: {
 *         username: "superadmin",
 *         name: { am: "ሱፐር አድሚን", en: "Super Admin" },
 *         roleKey: "super_admin",
 *         organizationKey: "edr_freight",
 *         unitKey: "edr_freight_app",
 *         fallbackEmail: "superadmin@tria.com",
 *       },
 *     })
 *
 * Any section left out keeps the value from `DEFAULT_IAM_BASELINE_SEED`. The
 * seeder needs a TypeORM `DataSource` that can reach the `iam` schema; the app's
 * default one is used, so `TypeOrmModule.forRoot*` must be registered.
