This update simplifies the way Odoo interacts with IoT devices by removing an unnecessary layer of code. The shift to the `iot_http` service allows direct access to devices through related models, improving efficiency and reducing complexity. This change enhances the overall system performance.

As we now use the `iot_http` service instead of the `iot_longpolling` one, we don't need to add the `DeviceController` layer on devices.

We now directy use the devices from related models.
