GitHub silently enabled RFC 9207 (OAuth 2.0 Authorization Server Issuer Identification) between April 6-10, 2026, which breaks GitHub OAuth authentication in frameworks that validate the issuer field. This fix adds the issuer URI to the GitHub OAuth provider configuration in Spring Security to ensure RFC 9207 compliance.
