feat: Add BOM version activation feature and enhance BOM management

- Implemented the `activateBomVersion` function in the BOM controller to allow activation of specific BOM versions.
- Updated BOM routes to include the new activation endpoint for BOM versions.
- Enhanced the BOM service to handle version activation logic, including status updates and BOM header version changes.
- Improved the BOM version modal to support version activation with user confirmation and feedback.
- Added checks to prevent deletion of active BOM versions, ensuring data integrity.
