feat(Wind): Load product.json at build time for configuration

Implement Atom I5: refactor ResolveConfiguration to fetch product identity from /product.json (generated by Maintain/Script/ResolveProductConfig.sh from .env.Land variables) instead of hardcoded strings.

- Add LoadProductJson() async function that fetches /product.json with fallback to minimal defaults
- Update product configuration fields (nameShort, nameLong, applicationName, version, commit, urlProtocol, dataFolderName, serverApplicationName) to use resolved values
- Preserve backward compatibility: network failures fall through to base defaults allowing degraded boot with version mismatch warning

This enables single-source-of-truth product identity without hardcoded version strings in the codebase. The Target/ build outputs are regenerated to reflect the new configuration resolution.
