Sync-Fix, Dateinamen mit Leerzeichen, E-Mail-Dropdown, Defaults-System

- Fix: Pull überschreibt lokale Vorlagen nicht mehr (Merge statt Replace)
- Fix: toFilename behält Leerzeichen und Groß-/Kleinschreibung
- E-Mail in Settings ist jetzt ein Dropdown mit TB-Identitäten
- Optionale defaults.local.js für vorkonfigurierte Verbindungsdaten (.gitignored)
