gpx import and waypoint features

> The waypoints are important in the CarPlay display with a desired touch function to bring up the waypoint name and notes. I also import waypoints alone without immediately using them in a route (the what-if thing), but once again, no current CarPlay apps have the waypoint touch functionality.

Start by reviewing Pelican's existing GPX import behavior and CarPlay display handling, since the issue names waypoint import, names, notes, and touch interaction but no files or tests. Clarify whether the work covers importing standalone waypoints, displaying waypoint details, or both; done should include an agreed scope and acceptance criteria for these interactions.
