    POST endpoint for zoning optimization.

    Purpose:
        Returns a static GeoJSON FeatureCollection of zones with crop suggestions

        and triggers "optimize zoning". No processing is performed on the request.

    Input parameters:
        - body (optional): JSON body; may contain a GeoJSON Feature with Polygon.
          Data type: object. Location: body. Not read or validated; not used in response.

    Response structure:
        - status: string, always "success".
        - data: object, GeoJSON FeatureCollection with features containing
          geometry (Polygon) and properties (zoneId, crop, matchPercent, waterNeed,
