This update strengthens the security of our Point of Sale (POS) system by ensuring that only valid access tokens are used when displaying customer information. The `PosCustomerDisplay` controller now verifies the access token, adding a layer of protection against unauthorized access. This change enhances the overall security posture of the Odoo POS module.

In this commit we adapt the `PosCustomerDisplay` controller such that it checks that the correct `pos.access_token` was sent.
