[Fonts] Make the editor's fallback and Reset preview-independent

- Add ThemeManager::defaultAppFont(), which resolves an unset role against the
  startup font instead of currentFonts, and use it in FontGridWidget::loadFonts
  so the grid never shows the live preview as the theme's default.
- Reload the live theme in PaletteEditorDialog::onReset before re-reading the
  grid, so Reset restores the saved fonts before loadFonts resolves fallbacks.
