fix: fan 100% on overheat, FCW fps-aware, commIssue suppress, 10min shutdown

- Fan controller: allow full 100% fan when offroad temp >= 75°C (startup cooling)
- ModelFps memory param: modeld publishes actual FPS (20 or 4) so downstream
  consumers can adjust frame-rate-dependent logic
- Longitudinal planner: dynamically adjusts dt and v_desired_filter based on
  ModelFps; FCW crash_cnt threshold scales with FPS to maintain consistent
  0.15s trigger window at both 20fps and 4fps
- controlsd: suppress commIssue alerts for 2s after lateral control engages
  (FPS transition from 4->20 causes transient freq check failures)
- Shutdown timer: hardcoded to 10 minutes (was 45min via FrogPilot param),
  screen taps reset the countdown via ShutdownTouchReset memory param,
  removed Shutdown Timer UI selector from ClearPilot menu
