fix(templates): prevent infinite redirect loop on unknown paths

[divyesh123-jain]

What?

Fixes infinite redirect loop on unknown/404 routes in production builds for templates with complex layouts (ecommerce, website, with-vercel-website).

Why?

In Next.js 15+, root layouts render statically by default. However, child components like AdminBar, Header, and Footer need runtime access to headers/cookies. This mismatch causes the layout to attempt re-rendering multiple times when users navigate to undefined routes in production builds, resulting in an infinite redirect loop and "too many redirects" browser error.

How?

Added await headers() at the start of the RootLayout function to force dynamic rendering, ensuring child components have access to runtime headers/cookies.

Changes:

• templates/ecommerce/src/app/(app)/layout.tsx - Added headers import and await headers() call
• templates/website/src/app/(frontend)/layout.tsx - Added headers to existing import and await headers() call
• templates/with-vercel-website/src/app/(frontend)/layout.tsx - Added headers to existing import and await headers() call

This doesn't seem like the ideal fix to me:

1. You have unrelated changes in the next package
2. You're opting the entire frontend into dynamic rendering by calling the headers there

Closing on that basis
