/**
 * Dedicated config namespace for the IAM **TypeORM** connection — the shared `iam` schema ONLY.
 *
 * This is intentionally separate from Prisma: Prisma remains the app's primary ORM and owns the
 * `passenger` schema via `DATABASE_URL` (see prisma.service.ts). This second connection exists
 * solely because `@tria-plc/api-common` / `@tria-plc/iamapi-common` are TypeORM-based and the
 * `JwtGuard` reads `iam.sessions` through a TypeORM `DataSource`.
 *
 * Consumed by `TypeOrmModule.forRootAsync` in app.module.ts.
