Create a NestJS REST API module for user management with:
1. JWT authentication (access + refresh token)
2. Redis-based token blacklist
3. PostgreSQL with TypeORM
4. CRUD endpoints for users
5. Input validation with class-validator
6. Unit tests for auth service
7. Integration tests for user controller

Use the existing NestJS project structure. Don't create a new project.
