fix(electron): pre-create userData dir for Windows + stream logs in CI

Windows smoke test exits code=0 because requestSingleInstanceLock()
fails silently when the APPDATA/<productName> directory doesn't exist.
Pre-create the directory so the lock file can be written.

Also enables ELECTRON_SMOKE_STREAM_LOGS=1 in CI for better debugging.
