phase 1: scaffold D3/TopoJSON migration structure

- Extract country prison data to assets/data/countries.js (ES module)
- Add ISO numeric→alpha-3 lookup table for TopoJSON ID bridging
- Download world-atlas countries-110m.json (TopoJSON, 108KB)
- Create stub ES modules for map, charts, and UI layers
- Replace ZingChart/jQuery script tags with single ES module entry point
- Preserve original app.js as _app.js.bak for Phase 2+ reference
