Add filters in the index action of the autogenerate crud

Add a template to have filters field working in the index action create by the autogenerate crud, as yii or symfony.


Look at the autogenerate crud code to understand how the index action is created. Examine existing templates for CRUD generation to see where filters could be added. The goal is to add a template that includes filter fields similar to Yii or Symfony frameworks. Check for any existing filter implementations or related code in the project to understand the expected structure.
