* chore: update react router to v8 and modernize node infrastructure

- Bump React Router to v8.0.0 and update associated dependencies.
- Upgrade Node.js base image to v24.
- Simplify TSConfig and Vite configuration by utilizing native TSConfig path resolution.
- Add .env to gitignore.
- Ensure consistent scripting and environment settings across SPA and SSR examples.

* test(node): bind React Router preview server to IPv4 in SPA example

- Force preview host to 127.0.0.1 in Vite config and generation script.
- Prevent connection mismatch issues between prerender requests and the preview server.
