Website Sale Loyalty Suggestion Wizard Multi Product

This module extends the website promotion suggestion wizard so that multi-product promotions can be configured and applied from the shop cart.

When a customer opens the cart and a promotion is active in the session, the module checks whether the promotion's rule uses the multi-product criterion. If so, it prepares the reward wizard for that order and promotion, selects a product to work with, and recalculates the promotion lines. The chosen product is stored in the session so it can be reused later.

• The cart page receives the list of mandatory promotion options so the wizard can show them.
• When the customer processes the promotion lines, the module restores the previously selected product, recalculates the rule lines, and automatically fills in the missing units up to the required quantity for each line that is not yet complete.
• The wizard template is adjusted so that the mandatory options block is displayed when there is exactly one mandatory option or when the wizard is handling multiple criteria.

It touches the website cart flow and the loyalty program, sale order and wizard models used by the underlying promotion modules. No new menus or standalone screens are added; the changes appear inside the existing website promotion wizard.
