Sale Coupon Portal Commercial Partner Applicability

This module extends the customer portal so that coupons are shown for the whole company (the commercial entity), not just for the individual logged-in contact.

When a portal user opens the coupon page, the module widens the search for coupons: it keeps the coupons that were already visible and adds those whose customer is the user's company or any contact belonging to that company. This means a contact person can see coupons earned by the company or by another contact of the same company.

It works together with the portal coupon feature and the commercial partner applicability rules, so the coupons displayed follow the company-level ownership logic. No new menus, buttons, reports or scheduled actions are added by this module; the change is limited to how the list of coupons is filtered on the existing portal page.

It touches the coupon portal controller and relies on the commercial partner concept on the customer record. No new database models are defined.
