Luồng xử lý chính

User truy cập frontend (React) qua port 3000

Frontend gọi API qua Kong (port 8000): /api/auth/*, /api/account/*, /api/transfer/*, /api/notifications/*

WebSocket /ws dùng cho thông báo real-time khi có chuyển khoản mới

Kong route request đến đúng service backend

PostgreSQL lưu users, balances, transfers, notifications

Redis lưu session (đăng nhập), presence (online), và Pub/Sub cho thông báo real-time
