mount_device() used a bare os.makedirs() to create the mount point,
but the app runs as an unprivileged user while /mnt is root-owned -
surfaced as a real PermissionError during the first actual hardware
test. Create the mount point via sudo mkdir -p instead, consistent
with the existing sudo mount/umount calls in this module.

First real-hardware test revealed the connected dashcam's SD card ships
factory-formatted with no partition table - lsblk reports it as a bare
"disk" with an fstype set directly, never as a child "part". The
previous detection logic only matched type=="part", so it silently
missed this real device entirely.
list_usb_storage_partitions() now also matches whole-disk USB devices
that have no children and an fstype set directly on them, in addition
to the existing partition-table case. Verified against a fixture built
from this dashcam's actual `lsblk -J` output.

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.
