Feature: Bank-Zuordnung zeigt Ausgangsrechnungen inkl. Rechnungen ohne Beleg

- Eingabe-Spalte aus Beleg-Liste entfernt (alloc_betrag als Hidden-Field)
- Beleg-Liste nach Datum neu->alt sortiert
- Ausgangsrechnungen ohne Bank-Link in offene Belege aufgenommen
- Rechnungen mit fehlendem Beleg (beleg_id IS NULL) werden angezeigt
- Beim Verknüpfen solcher Rechnungen wird Beleg-PDF automatisch erstellt
