Mails wurden bisher nur als Klartext verschickt. sendMail/sendTemplateMail
verschicken jetzt zusätzlich eine einfache, mandantenfarbige HTML-Version
(renderTemplateHtml in @kc/platform/mail): ein Platzhalter, dessen Name auf
"Link" endet, wird darin zu einer Schaltfläche statt einer nackten URL; der
Klartext-Teil behält den Link weiterhin sichtbar (Fallback für Mailprogramme
ohne HTML-Ansicht).
ticket_created/ticket_message bekommen dafür eine neue Variable
{{ticketLink}}, invoice_issued {{invoiceLink}} (Migration 025 – nur
Vorlagen mit noch unverändertem Text werden angepasst, damit von Personal
bereits bearbeitete Texte nicht überschrieben werden).
