fix: live-update Speed and WPM cells during benchmark run (v1.12.11)

Previously the bench/wpm cells only updated after loadVoiceLibrary() at
the end of the full batch. Now each row is patched in-place immediately
after its voice finishes, for both batch and single-voice benchmarks.

+### Fixed
+- **Speed and WPM cells now update live** during a benchmark run — each row's cells are patched in-place immediately after its voice finishes, without waiting for the full batch to complete and the list to re-render. Same fix applied to the single-voice "Benchmark this voice" button.
