Bugfix: Cloud: be more specific about session error codes (#6051)

InvalidClientTokenError indicates an unrecoverable state for
the session, so we need to be more exact about triggering it. A recent
Clerk outage resulted in a lot of 429 responses which should really cause
inactive-session, not a full clear to logged-out.
