sys-ctl-rpr-docker-hard: Refactor restart script with argparse & update systemd ExecStart

- Removed unused soft restart function and switched to argparse-based CLI.
- Added --only argument to selectively restart subdirectories.
- Updated systemctl service template to pass PATH_DOCKER_COMPOSE_INSTANCES as argument.
- Ensures service unit correctly invokes the Python script with target path.
