[P0] Fix unresolved @splinetool import on landing page

The new landing page imports @splinetool/react-spline/next, but the package that was added to package.json only exposes @splinetool/react-spline. Running pnpm exec next build fails with Module not found: Can't resolve '@splinetool/react-spline/next', so the app cannot compile. Import from the actual published entry point (and mark the component as client-side if needed) so that the build succeeds.
