`pos_loyalty` demo data were loaded as plain data.

This fix updates how manufacturing work order pedals communicate with connected devices. It helps prevent pedal input failures caused by earlier interface changes, making shop floor workflows more reliable.

`pedal_form` used to call the `iot_longpolling` and the call to
addListener wasn't adapted even though its signature was changed in
odoo/enterprise#11708. To avoid this kind of errors in the future, we
use DeviceProxy to communicate with pedals.
