Matt c8e2568f64 perf(offroute): query_radius uses k-NN <-> ordering for index-supported nearest-neighbor 
The old ST_DWithin(50km) scan returned ~226k candidate points near dense areas before
sorting (~3-10s/call). Replace with PostGIS k-NN ordering: ORDER BY geom::geography <->
point LIMIT k, which the existing GiST index on (geom::geography) walks nearest-first and
stops after K rows. SELECT still computes ST_Distance AS distance_m so callers see real
meters. radius_km is kept as a Python soft cap applied after fetch (drops rows beyond it),
preserving the caller expanded-radius fallback (now effectively a no-op).

2 tests: SQL contains <-> + LIMIT and no ST_DWithin; radius_km soft cap filters beyond-cap rows.
