Sam Rolfe 396eeb175e content: car tracker page with a real hardware image

- content/edge/l3/edge-car-tracker.md, written from the evidence notes
- product image of the SIM7080G Cat-M module, cropped to 640px, with a caption
  naming what it is and that it is a product image
- referenced from the edge overview
- original kept in sam/CAR_GPS_TRACKER so the project repo documents its own build

The devices are outdoors on solar and asleep most of their lives, and they have to keep working when nobody is looking; what failed is written down. The architecture, the radio and the failures are on the fleet page.
