Fix refreshFormData with Enum

[fouteox]

Description

If you use refreshFormData on values that are cast as Enums in the Model, the enum will be loaded instead of its value, which will cause a problem when submitting the form.

My PR fixes this problem by iterating through the values to refresh and taking ->value in the case of an Enum.

The solution is certainly not perfect for Filament's framework.

I'll let the experts correct this properly :)

• Visual changes (if any) are shown using screenshots/recordings of before and after.

Code style

• composer cs command has been run.

Testing

See my previous comment for this.

When the form is first loaded, the value is an enum instead of a string. Right?

[fouteox]

Nope, the first time the component is loaded with the form, it is indeed a string, even if the field is of type Enum.

The issue only occurs when using the refreshFormData function with a casted Enum field.
