fix(article): fix API Responses and paths

[mubbi]

This pull request refactors the namespace structure for API resources and requests, introduces a new MetaResource class for improved meta data handling, and updates the GetArticlesController to align with these changes. The updates improve code organization and enhance the clarity of API responses.

Namespace Refactoring:

• Renamed app/Http/Requests/Api/V1/Article/GetArticlesRequest.php to app/Http/Requests/V1/Article/GetArticlesRequest.php and updated the namespace to App\Http\Requests\V1\Article for consistency with the new structure.
• Renamed app/Http/Resources/Api/V1/Article/ArticleResource.php to app/Http/Resources/V1/Article/ArticleResource.php and updated the namespace to App\Http\Resources\V1\Article.

Introduction of MetaResource:

• Added a new MetaResource class in app/Http/Resources/MetaResource.php to encapsulate meta data transformation logic. This ensures a consistent structure for meta data in API responses.

Updates to GetArticlesController:

• Updated the namespace imports in GetArticlesController.php to reflect the new structure and include MetaResource.
• Modified the response structure in GetArticlesController to use MetaResource for the meta field, improving the readability and consistency of the meta data. [1] [2]

Updates to ShowArticleController:

• Updated the namespace for ArticleResource in ShowArticleController.php to align with the new structure.
