- Updated `User` class to use `required` keyword for `DateFormat` in .NET 7.0 or greater.
- Marked methods in `Extensions` and `AddUserManagerInfrastructure` as obsolete, suggesting the use of IRepository.
- Adjusted import statements in `DependencyInjection.cs` and marked `GroupOfUserRepository` and `ModuleRepository` as obsolete, recommending a Repository pattern.
