Reset ClickHouse setting to default

Disclaimer: This beta endpoint is evolving; the API contract may change.

Removes a previously-configured ClickHouse setting, reverting its effective value to the platform default. Settings under spec.extraConfig.server.* (e.g. keep_alive_timeout, shared_merge_tree_disable_merges_and_mutations_assignment) trigger a ClickHouse server rollout restart; other settings propagate to all replicas after a short delay. Deleting a setting that was never configured is a no-op (200 OK).
