fix(shim): restore nspace attest key lookup

Reverts 5f72acb. The nspace attestation key lookup was part of
the score-4 baseline and closes a real NPE on KEY_ID-domain
references where the alias field is null. Reverted in error
during the score-4-to-14 rollback; restoring to match the
working baseline.
