Add disable functionality to child.cmd script

Implemented a new command to handle the 'disable' action, which creates a disable file and logs the current date and time. Updated the reset functionality to also delete the disable file if it exists, enhancing the script's operational control. This change improves the script's robustness by allowing for a clean shutdown process.
