Fix bleak 3.x compatibility and code review cleanup

- Fix scan_for_onecontrol() to use return_adv=True and adv.service_uuids
  (device.metadata removed in bleak 3.x)
- Add missing _parse_get_devices_response() — was called but never defined,
  would crash on first real device response
- main() now auto-connects when exactly one device is found via scan
- Remove premature turn_on/off_light(5) calls from main() — device IDs
  unknown until get_devices() has been run against real hardware
- Guard send_command() and disconnect() against unconnected state
- control_awning() now takes MovementState enum instead of raw int
- Bump post-get_devices sleep from 2s to 5s for real device latency
