drop_off_points (with SPATIAL INDEX on coordinates) +
drop_off_capacity_logs. Public nearby query via ST_Distance_Sphere
returns DOPs sorted by distance with distance_meters in payload.
Admin CRUD plus capacity-log endpoint. Household creation auto-assigns
to the nearest active DOP within 25km; resident can re-run the lookup
via POST /households/{uuid}/reassign-drop-off.
97 feature tests passing.
