Enrich photos near the (north) pole

Running Dawarich 1.10.3 on Debian (TrueNAS)

This is similar to that other report I made, with lines curving on the globe view but not the flat view. Well, this extends to enriching photos as well.

Trying to interpolate the location of a photo I took of the in-flight monitor when flying over the North Pole. I can accept if it requires too much computing power to render all lines correctly on the globe, but at least photo location interpolation should be done correctly and precisely.

That preview of the photo location is nowhere near the straight line between the two points.

No file, test, or entry point is identified in the issue. Reproduce the North Pole photo-interpolation case on Dawarich 1.10.3 and trace the location calculation from the two surrounding points; done means the photo preview follows the correct straight path between them rather than the visibly displaced route.
