Step 2: Add Users microservice with API Gateway routing

- Created Users service with full CRUD operations
- Updated Console to act as API Gateway for Users service
- Implemented service-to-service communication
- Added service health monitoring in Console
- Docker Compose now manages both services

Services running:
- Console (API Gateway): http://localhost:8011
- Users service: Internal network only

Test endpoints:
- Status: curl http://localhost:8011/api/status
- Users: curl http://localhost:8011/api/users/users
