Store surface observations (ASOS) and upper-air soundings (RAOB) alongside QSOs for atmospheric propagation correlation. Three new tables: weather_stations, surface_observations, and soundings with JSONB profiles and pre-computed derived parameters (refractivity, gradients, duct detection, stability indices). Includes IEM API client for historical data import and import script seeded with 95 ASOS + 9 sounding stations from PropCast coverage area.
