Add edit() endpoint to controller with transaction, UseCase, and ViewModel integration

[zigzagdev]

Description

This PR implements the edit() method on the post controller to handle post editing requests. The method is responsible for:

• Receiving an HTTP request (Illuminate\Http\Request)
• Merging route parameters with request body
• Building a validated EditPostUseCommand
• Executing the EditUseCase to persist changes
• Returning a formatted JSON response via EditPostViewModel

Additionally, transaction control and exception rollback are implemented to ensure database integrity.

Why

This implementation closes the loop between Presentation and Application layers. By combining command parsing, transaction control, and ViewModel output, we ensure a cohesive and robust update flow.

How

• Added edit() method to controller

  • Wraps logic in DB::beginTransaction() / commit() / rollBack()
  • Uses EditPostUseCommand::build() with merged data
  • Injects EditUseCase and wraps output in EditPostViewModel

• On success: returns 200 OK with JSON payload

• On failure: returns 500 with error message

• Added integration-style controller test to verify:

  • UseCase is called with correct data
  • ViewModel transforms response correctly
  • Transaction boundaries are respected

[zigzagdev]

• Confirmed that merged input contains route + body data for command build
• Ensured transaction is committed only on success
• Verified rollback occurs on exception
• ViewModel formats response correctly
• Test covers both success and failure paths
• Used Mockery::overload to mock Request
• Used Mockery::on() to match command input strictly

• [nitpick] The parameter name $user_id (and similarly $post_id) uses snake_case. For consistency with PSR and the rest of the codebase, consider renaming to $userId and $postId.

        int $user_id,

• The test only verifies the response type. Consider adding assertions for the HTTP status code and the JSON payload to fully cover success and error scenarios.

        $this->assertInstanceOf(JsonResponse::class, $result);

• The code catches Throwable but Throwable is not imported. Add use Throwable; at the top of the file to avoid an undefined class error.

        } catch (Throwable $e) {

• The test stubs Request::all() but the controller calls Request::toArray(). You should mock toArray() instead (or call all() in the controller) to ensure the test returns the expected data.

            ->shouldReceive('all')

• [nitpick] The namespace repeats Presentation. Consider flattening to App\Post\PresentationTest\Controller to avoid redundancy and improve clarity.
