fix: stop extending API key access if OIDC refresh is available (cherry-pick #17878) (#17961)

Cherry-picked 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.

https://github.com/coder/coder/issues/17070#issuecomment-2886183613
explains why this is the correct behavior.
