fix(ui): never hang on a blank frame when the hub is unreachable

Browse source 
main() awaited the hub health probe before runApp(); a gRPC-web
error out of HubRepository.connect propagated and left the app on a
white page. Guard the settings+probe in main() with a MockRepository
fallback so the first frame always paints.
