Improve error handling and logging for rights and indexing

Enhanced error handling in ClassWD_Rechte to unlock objects after exceptions and prevent resource locks. Refactored frmNIHauptseite to add detailed debug logging and robust error handling in File_SetBooleanIndex, including better handling of missing or invalid index values. Replaced SetErrorMeldung with File_SetBooleanIndex for AD post-processing errors. These changes improve traceability and reliability.
