ModelFormMetaclass
This class is a metaclass used to create form classes that are tied to database models. It automatically extracts and configures form fields based on the model's definition, handling metadata options such as field inclusion, exclusion, and custom widgets. The metaclass also validates the configuration of the form's inner Meta class to ensure proper field mapping and error handling.
