Refactored annotation processing in PDFBurner.vb to handle null elements and annotations safely, preventing possible errors and improving code clarity. Updated GetSignedDate in ReceiverModel.vb to ensure consistent DateTime return values, handle DBNull and type conversions, and improve error handling.
Updated ReceiverModel and EnvelopeEditorController to utilize ReceiverVM instead of Receiver in multiple function signatures. This change enhances the structure and flexibility of receiver data handling. Adjusted related methods in frmEnvelopeEditor to align with the new view model approach.
