Replace completeStatementForClose/flushForClose toggle pattern with a closing flag that suppresses batch-triggered fire-and-forget flushes. Set closing=true first so completeStatement works normally via addPendingMetric (closed is still false), then seal with closed=true and drain with a single awaited flush(false).
