fix(desktop): sign embedded backend via mac.binaries for notarization

-/**
- * electron-builder afterPack hook.
- *
- * The Python backend is a PyInstaller onedir bundle shipped via extraResources
- * into Contents/Resources/backend/. electron-builder's deep signing does NOT
- * cover extraResources, so its executable + hundreds of .so/.dylib files stay
- * unsigned — which makes notarization reject the whole app.
- *
- * This hook runs before electron-builder signs the .app: it code-signs every
- * Mach-O file under the backend dir with hardened runtime + entitlements, so
- * the outer app signature and notarization succeed.
