    Fix txn_box unused find result (#13291)
    
    Clang 22 treats the ignored std::unordered_map::find result in the
    txn_box unit perf test as a warning, and the project builds with
    warnings promoted to errors. The test therefore fails to compile even
    though the lookup is intentionally only being timed.
    
    This explicitly discards the lookup result in the benchmark lambda and
    corrects the printed label to describe the lookup operation.
