Verlauf zeigt Mengen in Artikeleinheiten (Gebinde) statt nur Basiseinheit

MovementOut liefert jetzt package_size, package_label sowie Name/Faktor der
Anzeigeeinheit mit. Die Verlauf-Tabelle zeigt die Bewegung als Leitangabe in
Gebinden (z.B. "1 Glas") und darunter klein die Basiseinheit ("195 g").
Ohne Gebinde/abweichende Einheit bleibt es bei einer Zeile.
