This commit introduces a new AJAX functionality to check for duplicate bib numbers during the registration process. It adds a case in `ajax_inscr_gestion.php` to handle duplicate checks, returning relevant participant information and policies for handling duplicates. The front-end script in `inc_footer_scripts.php` is updated to incorporate this check before saving a bib, enhancing user interaction with confirmation dialogs for duplicate assignments. Additionally, new functions are added in `inc_fx_inscriptions_gestion.php` to manage duplicate policies and retrieve existing participants with the same bib number, improving data integrity and user experience in the registration management interface.
