📝 Walkthrough

Walkthrough

This pull request adds a changeset for a patch release and fixes a bug in the OAuthConsent component. The component's primary user identifier logic is updated to use a combined primaryIdentifier that prefers emailAddress and falls back to phoneNumber, replacing the previous emailAddress-only lookup. This modification ensures the OAuth consent screen displays the appropriate user identifier in the header subtitle when using a phone-number-only authentication flow, preventing "undefined" from appearing in the consent message.
