Toolbar-Button Fix, QuickMove-Tab, Schlagwörter-Sync, Abteilungsverwaltung

- Toolbar-Button öffnet Settings via browserAction.onClicked statt defektem Popup
- Button-Label "Vorlagen & Signaturen" statt Icon
- Tab "Erledigt" → "QuickMove" umbenannt
- QuickMove: E-Mails markieren + in Zielordner verschieben
- Schlagwörter-Sync aus Gitea (_config/schlagwoerter.json)
- Abteilungen anlegen (+Button)
- attachSignature-Fix entfernt
- message_display_action für QuickMove-Button
