App 2.17.1: tidier Settings and Logs

- Settings: the Wi-Fi and saved-networks cards are gone, and the rest
  sits in three columns (display and steering wheel | battery |
  charging price and app) instead of one tall column. The background
  Wi-Fi auto-connect stays on, without a switch.
- Logs: only the upload log. The steering-key reports, the car-colour
  probe and the screen line answered their questions and are removed,
  with their code (CarColorProbe, the key-report log) and strings.
- README lists the current tabs.
