brianhansonxyz b287fd094e make baseline build & launch cleanly
- onroad.cc: fix screenDisplayMode reference to nvg->screenDisplayMode
  (baseline had a stale reference to the variable after it moved into
  AnnotatedCameraWidget). Restores the original conditional intent.
- ui/SConscript + home.cc: drop QtWebEngine include/link entirely
  (no longer used by any active code).
- build.py: BUILD_ONLY env var spawns the failure TextWindow fully
  detached (own session, /dev/null stdio) so build_only.sh exits and
  caller can capture stderr; spinner binary update uses temp+os.replace
  so a running spinner doesn't ETXTBSY the build.
- build_only.sh: tee build output to /tmp/build.log and propagate
  build.py's exit code via PIPESTATUS.

Verified: build_only.sh completes cleanly, launch_openpilot.sh boots
the manager and spawns the standard process set.
