Enhance Users Service and DTOs

- Added Default trait to UsersDetailItemDto for easier instantiation.
- Refactored UsersServiceTrait to use Pin<Box<dyn Future<...>> for async functions, improving compatibility with async/await.
- Updated all service methods to return futures instead of using async_trait.
- Improved error handling and logging in upload_file method, ensuring proper handling of multipart data.
- Masked sensitive information in Env struct's Debug implementation for better security in logs.
- Cleaned up Cargo.toml by removing unnecessary async-trait workspace dependency.
