Change engine SRID to 4326

Per a discussion with @Alexander-M-Waldman we might want to change everything to be stored in lat/lon natively so we don't have to rely on pre-transformed XYs in address_summary or transform on the fly. There seem to be some inconsistencies between pulling from the State Plane XYs in address_summary and pulling from the geom column of the geocode table.
