fix(app): the log written to the end of the closing, each step of it with its time; the Discord thread idle outside the driver mode

The log service stopped with applicationQuitOrder, so whatever was logged while the simulator closed was lost; it now runs until StopLogService() and writes out what came before. The closing logs each of its steps with the time since it began, to tell where a closing that hangs stops. Outside the driver mode the Discord thread spun a core in its loop, it now sleeps a second between the checks.
