Add Docker containerization with external PostgreSQL support

- Add docker-compose.yml with PostgreSQL and Redis environment variables
- Add Dockerfile for multi-stage .NET build optimized for production
- Add .env.template with database connection configuration
- Update Program.cs with JWT authentication and Docker logging
- Configure external database connectivity (tested working)
- Container successfully connects to external PostgreSQL server

Infrastructure milestone: API containerized and database-ready
