fix: do not display duplicate generator devices

- When connected AC genset is present at /generator/1, we display its controls.
- When relay connected genset is present at /generator/0, we display it.
- When neither relay/genset control service is present, but some AC inputs
  are configured to be GENERATOR, we display them.
