[FIX] point_of_sale: search_read with elevated access

Previously, users in the base.group_user group encountered an AccessError when attempting to read the ir.module.module model. This was due to the base_install_request auto-install mechanism being disabled, which removed the implicit read access that non-admin users previously relied on.

To resolve this issue, this commit updates the _load_pos_data method to explicitly elevate privileges using sudo() when calling search_read() on the model. This ensures that the operation is executed with administrative rights, allowing all users to retrieve module metadata safely, regardless of their group permissions.
