feat: Enhance BOM management with new header retrieval and version handling

- Added a new endpoint to retrieve BOM headers with entity join support, improving data accessibility.
- Updated the BOM service to include logic for fetching current version IDs and handling version-related data more effectively.
- Enhanced the BOM tree component to utilize the new BOM header API for better data management.
- Implemented version ID fallback mechanisms to ensure accurate data representation during BOM operations.
- Improved the overall user experience by integrating new features for version management and data loading.
