WifiConfiguration: New disable network status for no subscription

Add a new network disable reason to disable EAP network if
AT_NOTIFICATION notification code (1031) is returned. It indicates
user has not subscribed to the requested service.

Bug: 122921493
Test: Manually verified that device will not try to connect to the
EAP network if EAP authentication failed with 1031 code before.
