What it does
This resource model manages database operations for EAV form elements, which link attributes to form types in Magento's Entity-Attribute-Value system.
Developers use this class when working with customizable forms (like customer or address forms) to handle loading, saving, and ensuring uniqueness of form element configurations.
It automatically joins attribute data when loading elements to provide complete information about the associated attribute.
