fix(contact): align Mechanism panel with Propagation Analysis ducts

Browse source 
The radar-only RainScatterClassifier sees ducting only when HRRR's
pressure-level M-profile flagged it. Sounding-detected and gradient-
inferred ducts surface in elevation_profile.ducts via the analysis
pipeline — promote those into :tropo_duct so the Mechanism badge
agrees with the narrative.
