Login token handling fixed — cart now updates reliably

Previously, in some rare cases (such as when accessing quotes or switching to a customer account via token), the cart did not update immediately without a manual page reload or navigation.

This could cause confusion for customers if their cart contents did not match their expectations.

With this update, logging in using a token now ensures that both the session and the shopping cart synchronize instantly, without requiring manual refreshes.

This improvement significantly enhances the reliability of login links used in customer service workflows and delivers a smoother, more consistent experience for all storefront users.
