feat(auth): create a zero-OID for Subject Public Key
Created an explicit zero-OID which can be used for Subject
Public Key that do not have their own key identifier.
With this, all keys (including the subject public key) have
a proper key OID string so we don't need to make a special
case of null pointers when it comes to handling key OIDs.
