Ticketkarte und Admin an das neue Formular angepasst

- Ticketkarte: Response-Level-Auswahl entfernt; Service Type als
  "Fernwartung" / "Vor Ort" (altes "Off Site" zählt als Fernwartung)
- Admin > Konfiguration: Ticketarten, Systeme, Reaktions- und Leistungsarten
  ausgeblendet, da das Formular sie fest vorgibt; editierbar bleiben die
  Prioritäten, die Listen bleiben beim Speichern im Config-Dokument erhalten
- Kaputtes Trennzeichen "�" wieder "·" (Ticketkarte, Kundenliste, Kundendetails)
