v1.0.18: fix ON_CHANGE never starting, improve version display

- Start FileWatchService from SyncFlowApp.onCreate() for any existing
  enabled ON_CHANGE pairs — previously the watcher only started on
  device boot or explicit pair toggle, so existing pairs after an
  app update never got watched
- About screen now shows "Version X.Y.Z (build N)" updating
  automatically from BuildConfig on every release
