UI overhaul, VPN management, controlsd fix, screen recorder removal

- Fix controlsd crash: self.state.name AttributeError when state is int
- Move telemetry tlog import to module level in carstate.py (was per-frame)
- Remove FrogPilot screen recorder from UI (was crashing OMX on init)
- Ready screen: boot logo background, 8-bit READY! sprite, error states
  (panda not connected, car not recognized) with 10s startup grace period
- ClearPilot menu: always opens to General, QButtonGroup for sidebar,
  System Status uses ButtonControl, VPN toggle with process control
- Sidebar hidden on construction (no flash before splash)
- Status window: threaded data collection (QtConcurrent), panda detection
  via scene.pandaType (SPI, not USB), only refreshes when visible
- VPN: moved to system/clearpilot/, SIGTERM graceful shutdown, keepalive
  ping through tunnel, killall openvpn on disable, launched from
  launch_openpilot.sh instead of continue.sh
- Disable gpsd and dashcamd temporarily for perf testing
