Deactivates a Device Add-In on a specific database. Clears any auto-enrollment configuration (including auto-enrollment groups), unenrolls every currently enrolled device, then sets the Add-In status to Inactive in MyGeotab and MyAdmin. Only reseller users can call this method. This is the same operation exposed by the L1 Device Add-In Management UI's "Deactivate" action; it is intended for programmatic deactivation without visiting the MyAdmin UI. Re-activation is not part of this API — use the existing install/enrollment APIs to re-enable the Add-In on the database.
Idempotent: if the Add-In is already Inactive the call returns Success=true without re-issuing MyGeotab calls or unenrollment work.
