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.

This update introduces a new feature, Store.FieldList, to enhance how email data is managed within the Enterprise version of Odoo. This allows for more flexible and efficient retrieval of information from email messages, improving the functionality of key modules like sales and customer communication. It's a refactoring effort to modernize the system.

Enterprise counter-part.
