Replaced nullable fields with non-nullable properties for `Report` and `BasePdfBytes` to improve initialization and encapsulation. Updated `OnInitializedAsync` to use `BasePdfBytes` and added error handling for missing PDF bytes. Refactored report creation logic by removing `BuildFreshBaseReport` and `CreateReportInstance`, consolidating functionality into a new `CreateReport` method. Enhanced `CreateReport` to support both predefined and dynamically generated reports, simplifying the code structure and improving maintainability.
