Fetch elevation data along the path between two stations via the Open-Meteo Elevation API (with Open-Topo-Data fallback), compute Fresnel zone clearance, earth bulge, and knife-edge diffraction loss, and store the results per QSO. - terrain_profiles table with migration and TerrainProfile schema - ElevationClient with batched API calls and fallback - TerrainAnalysis with Fresnel/diffraction physics (ITU-R P.526-15) - TerrainProfileWorker on Oban :terrain queue - QsoWeatherEnqueueWorker enqueues terrain jobs automatically - QSO show page displays verdict badge and collapsible elevation table - Reorder show page: terrain, soundings, solar, HRRR, surface obs - Fix Dockerfile wgrib2 build (add cmake dependency)
