feat(abschluss): interne Notiz des Fahrers beim Abschluss

- CompleteDeliveryAcknowledgements.internalNote (optional, getrimmt,
  max. 2000 Zeichen) wird atomar mit dem Abschluss gespeichert
  (delivery_completions.internal_note)
- Bewusst keine delivery_notes-Zeile: loest weder die Kunden-Bestaetigung
  der Notizen aus noch erscheint sie im Notizen-Step der App
- Lieferbericht: eigener Abschnitt "Interne Notiz" mit Zeitpunkt und Fahrer
- Bericht: Betrag in "Betrag erhalten" ans Zeilenende (Helvetica setzt nach
  dem Euro-Zeichen zu eng)
