Improve: MCP efficiency & fix radius filtering

- Remove bloat fields (shape, objectid, etc), add sequential IDs
- Add lang param (he/en) for Hebrew/English text values
- Reduce JSON whitespace (indent=None)
- Fix distance_meters: extract centroid from WKT shape geometry
- Add search_coordinates to all address-based tool responses
- Fix radius filtering: properly filter deals beyond radius_meters
- Change default radius from 30m to 50m
- Fix get_deal_statistics: return NO deals (stats only)
