fix(monitor): improve logging messages

- Refactored the `fn_monitor_check_lockfile`, `fn_monitor_check_backup`, and `fn_monitor_check_install` functions in the `command_monitor.sh` file.
- Updated the logging messages to provide more concise and informative output.
- Replaced `fn_print_info_nl` with `fn_print_info` for consistency.
- Removed unnecessary line breaks in the logging messages.
