- Remove unused register_user() method and helper methods
- Remove legacy UserRegister schema (customer registration uses CustomerService)
- Remove wrapper methods that just delegated to auth_manager
- Simplify auth_service to focus on login and vendor access control
- Clean up tests to match simplified service
The only registration path is now /api/v1/shop/auth/register for customers,
which uses CustomerService.register_customer().
