Implement a `UserWithProfileManager` to automatically create a default user profile upon user registration.
This ensures that each user has an associated profile with default values (e.g., `UserName`, `IsAdmin`, `IsDeleted`).
Updates the database schema to reflect the change from UserId to UserProfileId in the UserProfileCompanyTableStat and UserProfileProductTableStat entities.
Establishes a link between DbUserProfile and DbApplicationUser,
allowing for better management of user-related information
and integration with ASP.NET Identity.
Renames DbUser to DbUserProfile and updates related entities and configurations.
