fix(iot-hub): show guide button for all installed devices with fallback

Show the guide icon on device cards for ALL installed items, not just
those with installState. If installState is available, opens the
read-only review dialog. If not (items installed before the feature),
falls back to the item detail dialog — same pattern as the installed
items page info button.
