feat(game-bridge): enhance error diagnostics and consolidate build output

- Add extensive debug logging with [GAME-BRIDGE] prefix for easier troubleshooting
- Enrich USER_REGISTRATION_ERROR messages with HTTP status, URL, trace IDs, request IDs, cf-ray, and response snippets
- Create fixUnityBuild.js script to consolidate all parcel-generated JS files into a single inline index.html
- Update build scripts to call fixUnityBuild.js after parcel build
- Ensure enriched error messages (with httpStatus/url/trace/reqId/resp) are returned to Unity for CI visibility
- Add browser feature detection logging (BigInt, fetch, ErrorCause, etc.)
- Log detailed HTTP error context when network failures occur (especially for IMX offchain registration)
- Update target browser to Chrome 137 for Unity and Unreal builds
