fix: stop extending API key access if OIDC refresh is available (#17878)
fixes #17070 Cleans up our handling of APIKey expiration and OIDC to keep them separate concepts. For an OIDC-login APIKey, both the APIKey and OIDC link must be valid to login. If the OIDC link is expired and we have a refresh token, we will attempt to refresh. OIDC refreshes do not have any effect on APIKey expiry. #17070 (comment) explains why this is the correct behavior.
