feat: Löschen-Schaltfläche zur ReceiverInputComponent hinzufügen und Verwaltung der Empfängerdaten aktualisieren

- Löschen-Schaltfläche zur `ReceiverInputComponent` hinzugefügt, um den Texteingang zu leeren
- Logik in `receiver_filter` implementiert, um eine leere Zeile hinzuzufügen, wenn ein neuer Empfänger hinzugefügt wird, und Zeilen zu entfernen, wenn Eingaben gelöscht werden
- Verwaltung der `receiverData` aktualisiert, um dynamische Hinzufügung und Entfernung von Zeilen basierend auf Eingaben zu berücksichtigen
