Fix device name, ImportScreen layout, and preserve folder default

- AndroidConnector: use model: field for display name instead of
  product: (which is a cryptic codename like 'o1quew' on Samsung)
- ImportScreen: clean up layout with ToggleRow helper, remove duplicate
  toggles, all 4 options in one Options section
- AppState: preserveFolderStructure defaults to true
