bench mode, ClearPilot menu, status window, UI introspection RPC

Bench mode (--bench flag):
- bench_onroad.py publishes fake vehicle state as managed process
- manager blocks real car processes (pandad, thermald, controlsd, etc.)
- bench_cmd.py for setting params and querying UI state
- BLOCKER: UI segfaults (SIGSEGV) when OnroadWindow becomes visible
  without camera frames — need to make CameraWidget handle missing
  VisionIPC gracefully before bench drive mode works

ClearPilot menu:
- Replaced grid launcher with sidebar settings panel (ClearPilotPanel)
- Sidebar: Home, Dashcam, Debug
- Home panel: Status and System Settings buttons
- Debug panel: telemetry logging toggle (ParamControl)
- Tap from any view (splash, onroad) opens ClearPilotPanel
- Back button returns to splash/onroad

Status window:
- Live system stats refreshing every 1 second
- Storage, RAM, load, IP, WiFi, VPN, GPS, time, telemetry status
- Tap anywhere to close, returns to previous view
- Honors interactive timeout

UI introspection RPC:
- ZMQ REP server at ipc:///tmp/clearpilot_ui_rpc
- Dumps full widget tree with visibility, geometry, stacked indices
- bench_cmd dump queries it, detects crash loops via process uptime
- ui_dump.py standalone tool

Other:
- Telemetry toggle wired to TelemetryEnabled param with disk space guard
- Telemetry disabled on every manager start
- Blinking red circle on onroad UI when telemetry recording
- Fixed showDriverView overriding park/drive transitions every frame
- Fixed offroadTransition sidebar visibility race in MainWindow
- launch_openpilot.sh: cd to /data/openpilot, --bench flag support
