Report a component failure (unenrolled device)

Called by the MineOS device agent when it fails before it holds a device certificate — for example when the installer or
the updater cannot complete; you do not call this endpoint yourself. The agent authenticates with your organization's
enrollment token and describes the failure; it may then upload a diagnostic log to the returned URL. The device identity
it reports is unverified and is used only to help MineOS support investigate.
