Oliver Kieselbach 2e736f40ad feat(backend,shared): Intune Enrollment Validation admits enrolled devices without pre-registration (D-282)
The certificate's Intune managedDevice id is looked up in the tenant's Intune. With the tenant
switch ValidateIntuneDeviceBinding on, that lookup is the last accepting link of the validator
chain: an enrolled device that is not being retired, wiped or deleted is admitted as
ValidatorType.IntuneEnrollment. A 404 for a certificate younger than 60 minutes is
NotFoundRecentEnrollment (503, never cached); a missing grant is 503 with 120 s.

For devices another validator admitted, the lookup only observes: in the background, never
admitting or rejecting, and only when the app token carries
DeviceManagementManagedDevices.Read.All, so a tenant without the add-on costs no Graph call.
Outcomes ride on the request row (CertDeviceBinding, role, serial match, owner and enrollment
type).

TenantConfiguration.HasAnyDeviceValidation() is the single gate precondition; the feature flags
expose it as deviceValidationEnabled (replaces validateAutopilotDevice).

The agent parses ValidatorType strictly: release the agent before this backend.
