Implement error handling and JSON response for ajax_inscr_gestion.php

Browse Source 
This commit enhances the error handling in the `ajax_inscr_gestion.php` file by introducing a shutdown function that captures fatal errors and returns a structured JSON response instead of a generic 500 error. Additionally, it adds diagnostic information for invalid actions, improving the debugging process. These changes aim to provide clearer feedback to users and developers when issues arise during AJAX requests.
