Add Functionality to Automatically Create Categories, Collections, Tags, and Types if Not Existing During Import Process

[Mazhar905]

To improve the import process, I propose adding a feature that automatically creates categories, collections, tags, and types if they do not already exist in the system. This enhancement will streamline the import workflow by eliminating the need for manual pre-creation of these elements, ensuring that all necessary components are in place for a successful import. The system should validate and generate these elements dynamically, reducing the risk of errors and improving overall efficiency. This feature will be especially useful in scenarios where large datasets are being imported, and the existence of these elements cannot be guaranteed in advance.
