[REQUEST] Upgrade to Next.js 15

[adriangalilea]

I was trying this amazing project, but the demo's won't work if upgraded to Next.js latest.

It'd be great to update the templates.

I'm not quite sure how to fix it myself in the time I had, because I don't know how to debug this:

next build "--debug"

   ▲ Next.js 15.1.7
