feat: Add BOM version initialization feature and enhance version handling

- Implemented a new endpoint to initialize BOM versions, automatically creating the first version and updating related details.
- Enhanced the BOM service to include logic for version name handling and duplication checks during version creation.
- Updated the BOM controller to support the new initialization functionality, improving BOM management capabilities.
- Improved the BOM version modal to allow users to specify version names during creation, enhancing user experience and flexibility.
