Subject: [PATCH] API Remove ALC renewal, tweak extension point

The ALC token is no longer rotated during an active login. Also removed related
`replace_token_during_session_renewal` config. The extension point that was
previously provided in the `renew()` method has been renamed and is now triggered
externally in the `CookieAuthenticationHandler::authenticateRequest()` method.
