      Saves the transaction changes and waits for completion synchronously. This method should not be used after the `commit()` or `commitAndWait()` method was already called once.
      - Important: Unlike `SynchronousDataTransaction.commit()`, this method waits for all observers to be notified of the changes before returning. This results in more predictable data update order, but may risk triggering deadlocks.
