Fix FAIL_UNAUTHORIZED re-queue loop when IV is disabled

Gate the FAIL_UNAUTHORIZED re-queue path on useIdentityVerification == true.
When IV is OFF, hasValidJwtIfRequired() always returns true so re-queued ops
were immediately eligible, creating a ~200ms infinite retry loop. Now IV-OFF
treats FAIL_UNAUTHORIZED the same as FAIL_NORETRY (drop + wake waiters).

Also fix Operation.externalId KDoc: subclass constructors set this field,
not IOperationRepo at enqueue time.
