fix(cli): keep docker's credential warning out of build logs

The registry login step's output was collected into the shared build log
buffer, so build logs on self-hosted and local builds always carried
docker's unencrypted-credentials warning. Filter those lines while the
rest of the login output (e.g. Login Succeeded) still flows through; the
login-failure path keeps the full login output.
