Subject: [PATCH] + `App\Controller\AssetController` like
 `Route::get('/assets/{filename}', ...)` in `be/routes/web.php`

+ `PrettyJsonResponse` & `ShowReactJsonView` like `App\Http\Middleware\DumpJsonResponse` in `be`
+ `SerializeToJson` for allowing controller methods to return an array instead of instance of class `Response` directly like laravel
@ `App\EventListener`

+ var `ASSETS_BASE_URL` for config `framework.assets.base_urls` in `config/framework.yaml` @ .env
@ symfony
