feat: implement volume restoration functionality

- Added a new restoreVolume function to facilitate the restoration of Docker volumes from backups.
- Integrated service type handling for both application and compose, ensuring proper scaling and management of services during restoration.
- Enhanced command generation for restoring volumes, improving clarity and maintainability of the logic.
