PTHSonde v1.5.1 — readable map prediction lines

Patch release on top of v1.5.0.

Fixed

• Map: flight prediction lines are now readable on every basemap. The predicted-path and baseline lines were thin, half-transparent, and gray, so they disappeared on the Satellite and Dark backgrounds. They're now drawn as a bold bright core over a dark halo — cyan ascent / orange descent, with the frozen GFS baseline as a lighter dotted reference — matching the flight-track styling.

All v1.5.0 features are included (Analysis ops panel + custom surface, self-contained SHARPpy, Open Past Flight, selectable basemaps).

Install
