Upgrade nextjs demos

[DavidWells]

Update the next.js app router demo at https://github.com/DavidWells/analytics/tree/master/examples/nextjs-app-router

Update all the next/react dependencies and modernize the code base while keeping the core functionality. Keep in the JS too dont convert to TS.

Next.js is on v15.3.4 https://www.npmjs.com/package/next

While you are at it, can you also add a similar demo but using the next.js pages router? Add to examples/nextjs-pages-router dir.

Thanks @claude
