No real-device magnetic implementation is present in the pinned protocol.

The real Lamzu and G-Wolves clients do not report magneticButtons or implement the magnetic setter methods. Therefore, magneticControls generates no magnetic controls for those devices. The new feature is limited to the mock path until the protocol adds the status fields and setter methods, and the desktop dependency updates to that implementation.

Review comment at @gpui/js/controls.ts around lines 479 - 502:
Limit magneticControls and the related setter cases to devices with protocol
support for magneticButtons and the magnetic setter methods, so real Lamzu and
G-Wolves clients do not expose unsupported controls. Preserve the existing
mock-device behavior and leave magnetic support ready for activation when those
protocol fields and methods are added.
