Add API endpoints and management pages for software versions and upgrade paths
- Implemented API endpoint for managing software versions in `products_software_versions.php`. - Created management page for software version assignments in `products_software_assignments.php`. - Developed upgrade paths management functionality in `products_software_upgrade_paths_manage.php`. - Enhanced software version details page in `products_software_version.php`. - Added form handling and validation for software version creation and updates in `products_software_version_manage.php`. - Introduced pagination and filtering for software versions in `products_software_versions.php`. - Implemented success message handling for CRUD operations across various pages.
