Like headers, but forces any cached authentication to
refresh before returning. Request layers call this after the server
rejects a request with an auth error (HTTP 401 / gRPC Unauthenticated)
so a stale-but-unexpired cached token is re-minted instead of failing
until its TTL. The default delegates to headers; auth providers
override it to bypass their session cache and re-authenticate.
