Support for Preserving All Translations with laravel-data + laravel-translatable

[gigerIT]

Hi, thanks for the great package!

We're using spatie/laravel-translatable together with spatie/laravel-data, and in most cases the auto-casting of translatable fields to the current locale (since v4.10 #870 ) works great. However, we have a use case where we need to retrieve all translations of a translatable field as an array, for example, when sending data to our backoffice to manage all locales in one view.

To achieve this, we experimented with a trait that adds a helper withAllTranslationsFrom() method to temporarily clear the $translatable property before passing the model to from():

namespace App\Support\Helpers;

use Illuminate\Database\Eloquent\Model;
use Spatie\LaravelData\Data;
use Spatie\Translatable\HasTranslations;

/** @mixin Data */
trait DataModelHasTranslations
{
    public static function withAllTranslationsFrom(Model $model): static
    {
        /** @var $model HasTranslations */
        $model->translatable = [];

        return static::from($model);
    }
}

This works fine for simple flat Data objects. However, it breaks down when dealing with nested data structures (e.g., nested Data objects or collections), as those nested objects still receive already-casted strings.

Has anyone dealt with this kind of issue before? Is there a recommended way to keep the full translation arrays available when mapping a model to a Data object? Or a way to configure laravel-data to avoid auto-casting translations at all in certain cases?

Thanks!
