refactor(annotation): generate deterministic annotation IDs based on envelopeId, receiverId, and element index

- Methoden für Annotationen (AddInstantJSONAnnotationToPDF, AddImageAnnotation, AddInkAnnotation, AddFormFieldValue) auf Rückgabe-Typ Void umgestellt.
- Interne Try/Catch-Blöcke und das Unterdrücken von Ausnahmen in Hilfsmethoden entfernt.
- Fehlerbehandlung in BurnInstantJSONAnnotationsToPDF zentralisiert, mit Try/Catch für das Hinzufügen von Annotationen.
- Exit Select-Anweisungen für bessere Lesbarkeit in Select Case-Blöcken hinzugefügt.
- Import von DevExpress.DataProcessing ergänzt.
