Disable HAL_USE_RTC usage (need for cmd_time)

Add ENABLE_TIME_COMMAND for enable cmd_time if need

Fix incorrect data on run cmd_scan cmd_data if Tansform enabled on NanoVNA (remove transform_domain() from sweep, add in front of plot_into_index in sweep thread)
Remove pause/run in reload (not need, command run vs CMD_WAIT_MUTEX flag)
