refactor: improve backup and update monitoring

The code in `command_monitor.sh` has been refactored to enhance the monitoring of backups and updates. The conditions for checking if a backup or update is running have been modified to include additional checks using `pgrep`. This change improves the accuracy of the monitoring process.
