chore(rsc-demo): preserve actual export names in SSR module map

- Update ssr-entry.js in both app1 and app2 to read export name from manifest
- Build module map with actual export name + standard fallbacks (default, *, '')
- Ensures React can access named exports during SSR rendering
- All 341 RSC tests pass
