NextJS 15 support

[braveltd]

nextjs 15 has been released - https://github.com/vercel/next.js/releases/tag/v15.0.0

Current nextjs version in template is 14!

leading to the conclusion that the template needs to be updated. At your next convenience, would you be able to do so?

Hi @braveltd,

I was playing around with this for a bit, but currently theres and issue with the @tonconnect/ui-react package and nextjs 15. Here's the issue.

I can open a draft pull request without the package for anyone who is looking to update and does not need said package and submit the full PR once the issue is fixed

Regards

[braveltd]

bump, still issue persists?
