This commit introduces new functions for managing payment session data, including `fxPaiementSessionComId`, `fxPaiementCanUseModesPromoteur`, and `fxPaiementCanUseModesAdmin`. These functions enhance the payment processing logic by determining the appropriate payment modes based on user roles (promoteur or admin). The existing payment display functions in `inc_fx_panier_js.php` are updated to utilize these new functions, improving the clarity and maintainability of the payment handling process. These changes aim to enhance user experience and ensure proper access control for payment options.
