controlsd: re-apply QoL hooks on top of reverted baseline

Re-adds the non-self-drive controlsd integrations that the UI and
memory-param pipeline need:

- import SpeedState from clearpilot.speed_logic
- self.speed_state, speed_state_frame, was_driving_gear init
- subscribe to gpsLocation (ignored in alive/freq_ok/valid gates — OK if
  the GPS daemon isn't publishing)
- clearpilot_state_control:
  - auto-reset ScreenDisplayMode 3→0 on park→drive transition
  - ~2Hz speed-state update driving the speed-limit sign and cruise
    over/under warning sign via ClearpilotCruiseWarning /
    ClearpilotSpeedLimitDisplay memory params

The debug-button (LFA) ScreenDisplayMode cycling already lived in the
reverted baseline (it was in the first commit), so it's preserved.
