Upgrade Notices

Authservice now automatically enables ServiceAccount token mounting when a chain uses client_secret_ref, fixing startup failures when token automounting was disabled. Deployments without client_secret_ref retain the existing hardened behavior. No user action is required unless you rely on the previous explicit automountServiceAccountToken: false behavior.
