- _decode_odometer: catch all exceptions and return None instead of raising.
PID 0xA6 (odometer) is not guaranteed on 2013 Toyota Yaris — a garbage
response or unsupported PID previously raised ValueError through python-obd's
decoder, which app_obd._query() caught and treated as a lost connection,
killing the entire OBD session. Now it gracefully returns None.
- connect_obd: reset all sensor globals (rpm, coolant_temp, fuel_level,
throttle_position, mil_on, dtc_codes, odometer, timestamps) on each new
connection so the UI doesn't display stale readings from the previous
ignition cycle while fresh polls are completing.
- yaris-obd.service: add commented OBD_PROTOCOL=6 hint for post-confirmation
pinning (eliminates 3-5s auto-probe delay after first confirmed connection).

Squashed rewrite of the project revival work (replaces prior history on this
branch to remove personal data that had been accidentally committed - real
LAN IP, GPS coordinates, home WiFi SSID, and phone model). See PLAN.md for
full phase-by-phase details. Summary:
- Phase 2: adapt app_obd.py for a USB OBD-II adapter (was Bluetooth-only),
auto-detect /dev/ttyUSB*, fix several pre-existing crash bugs.
- Phase 3/4: make the web UI work fully offline (vendored Socket.IO/Leaflet/
Chart.js/FontAwesome, offline map tile downloader script, live GPS marker
tracking fix).
- Phase 5: systemd deployment/autostart on the Pi.
- Phase 6: WiFi hotspot mode via NetworkManager (auto-switch between home
WiFi and a local AP for in-car web UI access), mDNS hostname + port 80
redirect so the UI is reachable at a plain hostname with no port number.
- Phase 7: fix app_db.py/app_sql.py bugs, wire up local SQLite trip logging.
- Phase 8: brand-agnostic USB dashcam file retrieval (lsblk transport-based
detection, works with any dashcam brand/folder layout).
- Rewritten readme.md with a proper project overview.
