[Fonts] Restore the startup font when a config has no InterfaceDefault

- Capture the untouched application font next to the default palette and use
  it in previewFonts' else branch, so a config without InterfaceDefault
  restores the startup font instead of leaving the last preview applied.
- Drop the unpolish/polish loop from previewFonts: QApplication::setFont
  already notifies every widget, and the loop ran on every editor auto-apply.
