handleLogout method

Implementation

Future<void> handleLogout() async {
  // Force refresh to ensure we don't use any stale cache after logout
  // This is critical for non-web platforms where SharedPreferences cleanup may be async.
  final places = await PlacesService.fetchPlaces(
    forceRefresh: true,
    includeEncrypted: false,
  );
  if (mounted) {
    setState(() {
      allPlaces = places;
    });
  }
}
