mandreshope 40ef71a28b refactor: Standardizes data model naming convention
Renames `AuthStruct` to `AuthModel` and `ProductStruct` to `ProductModel` to align with a consistent data model naming convention.

Updates all relevant imports, type declarations, and method signatures across the application to reflect these changes, improving codebase clarity and maintainability.

Includes minor code style improvements and refactorings in other components.
