port C++ UI from broken: ready/splash, ClearPilot menu, onroad widgets, nightrider

Wholesale port of the 10 UI files (main.cc, ui.{cc,h}, onroad.{cc,h},
home.{cc,h}, window.{cc,h}, ready.{cc,h}, SConscript). sidebar.{cc,h}
unchanged.

Brings in:
- splash/ready screen rendered via Qt directly (replaces stock home)
- ready page shown when started but gear=park
- ClearPilot offroad menu (Home/Dashcam/Debug panels) replacing stock
- onroad UI: speed widget reading ClearpilotSpeedDisplay (gpsLocation
  via speed_logicd), speed-limit widget, cruise-vs-limit warning sign
- nightrider mode: camera suppressed, lane lines/path drawn as 2px
  outlines only (ScreenDisplayMode 1 or 4)
- screen power: ScreenDisplayMode 3 forces setAwake(false)
- ignition off blanks screen immediately (tap still wakes)
- Qt-based RPC widget-tree dump server at ipc:///tmp/clearpilot_ui_rpc
- crash handler in main.cc with stack trace

Deviation from broken (3 sites): no_lat_lane_change is read from
paramsMemory (controlsd writes it there in baseline) instead of broken's
custom cereal field frogpilotCarControl.noLatLaneChange. Keeps the
existing self-driving wiring intact.

SConscript drops screenrecorder.cc from qt_src (broken did the same;
omx_encoder.cc still built for dashcamd's future link).

Build clean. UI hasn't been launched yet — that comes after the
controlsd button-handler commit lands.

Translation .ts files are auto-regenerated by Qt's lupdate; included.
