This update ensures consistency in how Odoo generates URLs. Previously, there were two ways to get a URL, and this change standardizes them, making the system more reliable. Developers can now explicitly use `.href` when a plain string URL is needed, improving code clarity and maintainability.

Makes it the symmetric counterpart of urlToState(url: URL). Call sites
that need a plain string use .href explicitly.

This update streamlines the handling of scales within our Point of Sale system. It adopts a new, standardized approach for scale operations, originally developed by the Odoo community, to improve reliability and maintainability. Initial support is available on PC browsers, with Android support planned for a future release.

The Community PR odoo/odoo#249723 refactors the scales to have a base `ScaleInterface` class, as well as moving the weighing logic and UX to community.

This commit adapts the `IotScale` and `CertifiedIotScale` to use the new system.

**Availability:**
Currently only PC browsers supported
Upcoming with Android version 17 with Chrome on Android >= 148
