feat(iot-hub): add Open Dashboard/Device button on last wizard step

Replace Done button on the last step with:
- Close (text button) — closes dialog
- Open Dashboard / Open Device / Open Gateway (primary button) —
  closes dialog and navigates to the entity

Priority: dashboard > device > gateway > integration.
If no entity was created, only Close is shown.
