dumpsites table with both coordinates POINT and boundary_polygon
POLYGON (SRID 4326). Admin CRUD accepts boundary as a list of {lat,lng}
points; ring is auto-closed. Dumpsite::containsPoint() runs ST_Contains
for geofence checks (Module 10 will fire arrived_at_dumpsite from this).
dumpsite_releases schema in place — trip_id stays nullable bigint until
Module 10 adds the FK.
109 feature tests passing.
