E-Mails und Druckvorlage im neuen Design

Browse source 
E-Mail:
- Nachrichten werden in ein markentreues HTML-Gerüst gelegt (Tabellen +
  Inline-Styles, damit Outlook & Co. es zuverlässig darstellen); die
  Kopfleiste nutzt den eingestellten Markenverlauf
- neuer Platzhalter {VOUCHER_CARD} rendert den Code als hervorgehobene
  Karte; bestehende Vorlagen mit {VOUCHER_CODE} funktionieren unverändert
  weiter, sie werden lediglich eingerahmt
- Zeilenumbrüche der Vorlage werden vor dem Einsetzen der Platzhalter
  umgewandelt, Markup aus dem WYSIWYG-Editor bleibt unangetastet

Druck:
- neue Standardvorlage als Ticket mit QR-Code, Code, Gültigkeit und
  Anleitung; zentral in Ui::defaultPrintTemplate()
- neuer Platzhalter {QR_CODE}; der QR-Code wird lokal im Browser erzeugt
  (qrcodejs aus assets/vendor), auch bei Bulk-Erstellung für jede Karte
- die Druckvorlage ist am Bildschirm ausgeblendet und erscheint nur im
  Ausdruck
