Description

This PR introduces the ability to configure the Faker locale, adds corresponding test coverage to ensure it's correctly applied, and refactors the factory method to utilize the ModelFactory helper.

Why?

This change supports the ability to set a custom Faker locale as documented in the Hypervel documentation.

💡 Tip: You can set the Faker locale by adding a faker_locale option to your config/app.php configuration file:

'faker_locale' => 'fr_FR',

This PR ensures the factory respects that configuration setting and generates localized fake data accordingly.
