The VoIP softphone now loads more recent calls and contacts as users scroll, instead of requiring all entries to appear at once. This makes browsing longer call histories and contact lists easier and keeps the interface more responsive.

Implement "infinite scrolling" in recent calls/contacts tabs.

Task-3984680

Point of Sale no longer needs extra country-specific customizations for blocking mixed refund and sales orders, because this behavior is now handled by default.

Community PR Odoo/Odoo#189329 changes the return value of the `PosOrder` method `doNotAllowRefundAndSales` to `true`, so that some patches are no longer relevant.
