Persist logbook JSON and photos in SAF so they survive reinstall

- LogbookStorage: reads/writes nav_logbook.json and photos into the SAF
  logbook/ subfolder, using the same saf_tree_uri pref as TrackStorage.
  Automatically migrates legacy getExternalFilesDir JSON on first SAF
  write. Falls back to external files when SAF is not yet configured.
- LogbookRepository: expose cameraDir (cache-backed temp for FileProvider),
  copyPhoto(Uri), and importPhoto(File) instead of the old photoDir.
- VoiceLogFragment / TrackDetailSheet: camera writes temp to cacheDir then
  imports to SAF after capture; gallery delegates to copyPhoto(); photo
  display and decodeThumbnail handle both content:// URIs and file paths.
- file_paths.xml: add cache-path entry so FileProvider can serve camera
  temp files from cacheDir/nav_camera/.
