Replaces the cramped Checkpoints disclosure with a real DataTable + a
side drawer (Logs / Config with snapshot/diff modes) and closes the
audit-log gap discovered in DeploymentController (deploy/stop/promote
currently make zero auditService.log calls).
Cap visible checkpoints at Environment.jarRetentionCount — beyond that,
JARs are pruned and rows aren't restorable. Logs scoped per-deployment
via instance_id IN (...) computed from replicaStates (no time window
needed). Compare folded into Config as a view-mode toggle. Two-phase
rollout (backend ships first to close the audit gap immediately).
