fix: pass wheel filename through extraction chain to fix micropip install

Browse Source 
micropip requires the full PEP 427 wheel filename (name-version-py-abi-plat.whl)
— writing the file as bincio.whl caused InvalidWheelFilename. The wheel URL from
/api/wheel/version now provides the basename; it flows through fetchWheelBase64 →
extractFile → WebView where the file is written with the correct name and
_wheel_path is set as a Pyodide global before PY_INSTALL_WHEEL runs.
