The self-ordering point of sale module now relies on the existing point of sale box module for printer box details instead of defining them again. This reduces duplication and helps keep configuration behavior consistent across related point of sale features.

Remove `proxy_obox_id` from `pos.printer` model, in `obox_pos_self_order` and change `obox_pos_self_order` dependency to `obox_point_of_sale` instead of `obox`.

The field `proxy_obox_id` is defined in `obox_point_of_sale` module.
