/**
 * CLI script to onboard a new tenant from a JSON file.
 *
 * Usage:
 *   npx ts-node src/cli/onboard-tenant.ts path/to/tenant.json
 *
 * JSON format:
 *   {
 *     "tenant_name": "Mellow Travels",
 *     "subdomain": "mellow",
 *     "admin_name": "Mellow Admin",
 *     "admin_email": "admin@mellow.com",
 *     "admin_password": "Admin@123"
 *   }
 *
 * The script bootstraps the NestJS app, calls TenantService.onboard(),
 * then exits. All seeding (roles, permissions, settings, currencies, etc.)
 * happens automatically via the existing onboard flow.
