Un-pydantic FlightWaypoint.

Apparently it's a bad idea to try to make the core data pydantic models,
and those should really be treated more as a view-model. Doing otherwise
causes odd patterns (like the UI info I had leaked into the core type),
and makes it harder to interop with third-party types.
