routes + route_stops tables. Admin CRUD with stops submitted as an
ordered array (drag-reorder is client-side; sequence is array-index).
Cloning produces an inactive copy with -COPY-XXXX suffix. RouteCalculator
recomputes total_distance_km via ST_Distance_Sphere across stop
coordinates + dumpsite, and estimated_duration_minutes from dwell time
+ travel time at config-driven avg speed (default 25 km/h).
default_team_id stays nullable bigint until Module 9 adds the FK.
139 feature tests passing.
