Overview

Extracts an OpenSSL verification key from a Model::KeyInfo.

Strategy (per spec ยง4.5): X509Certificate is preferred for key reconstruction because it carries the certified binding. Falls back to RSAKeyValue / DSAKeyValue / ECKeyValue if no certificate is present. KeyName is resolved via an application-supplied key map.
