Add Microwaveprop.Format.distance_km/1 and a matching formatDistanceKm helper for the JS side. Both emit "X mi (Y km)" with one decimal under 10 mi and whole numbers above. Replace the ad-hoc format_dist/format_km_mi helpers with the shared formatter and update every user-facing distance render: contact detail, contacts index column, user profile contact/involving tables, path finder summary + sounding list, contacts map line popups, beacon coverage tooltip, and propagation map range estimate + rain scatter cell popup.
