[Feature Request] Add live tracking

[A1CY0N]

Many thanks for all your great work on wanderer @Flomp. An additional feature that would surely be useful to many people would be to be able to record a live track with FOSS applications like OwnTracks, Compass or Overland.

This would require adding an endpoint to the API and adding a toggle (like the “public” one) with the URL when creating a trail.
