[matt-russo-notarize]

Adds the new US nationality scope.

• Updates CredentialID and Scope into default | nationality
• Adds national credential id to CREDENTIAL_IDS
• Updates verifyVPToken to initialize all credential ids to [] to match the VPToken's shape
• Adds tests to confirm scope is accepted and verifier behavior change is working

@matt-russo-notarize do we need a new subclass of ProofCredential in https://github.com/proof/proof-vc-common/blob/main/packages/server/src/proof_credentials.ts? If CI is passing, can we make sure we add a test that would break if you have need credential types without their class counterpart?

[matt-russo-notarize]

@frostevent I don't think we need a new subclass since it is still a ProofCredentialV1, I just needed to add is_national/us to ProofCredentialV1 and to the factory.

Also i added exhaustiveness checks for credential types<->classes and ids to confirm the unions are adhered to.

Why do we need CREDENTIAL_ID_SET?

[matt-russo-notarize]

it's so we check satisfies on compile to ensure no new CredentialType member is added without a matching class name.

added a comment about it and removed the export
