Fix React Server Components CVE vulnerabilities (#1)

Updated dependencies to fix Next.js and React CVE vulnerabilities.

The fix-react2shell-next tool automatically updated the following packages to their secure versions:
- next
- react-server-dom-webpack
- react-server-dom-parcel  
- react-server-dom-turbopack

All package.json files have been scanned and vulnerable versions have been patched to the correct fixed versions based on the official React advisory.
