Preis-Vorschlag: Auswahl aus mehreren erkannten Beträgen

Findet die Beleg-Analyse mehrere Beträge, liefert der Upload jetzt eine
Kandidatenliste (bester Tipp zuerst). Web und iOS bieten dann ein Dropdown zur
Auswahl des richtigen Kaufpreises, statt nur den automatischen Tipp. 1 neuer
Test; Backend-Suite gruen.
