Modified the `GetId<TId>` method in the `EntityExtensions` class to change its return type from nullable `TId?` to non-nullable `TId`, ensuring stricter type safety by throwing an `InvalidOperationException` when the `Id` property is not readable.
Removed a summary comment in the `ICRUDService` interface related to the `CreateAsync` method, which may indicate ongoing documentation updates for clarity on the method's functionality and parameters.
