CSV upload works after doing:

• paste postgres url directly into schema.prisma
• npx prisma db push - inits postgres

To fix Hydration Mismatch (only happens after file upload): removed metadata and added this to layout.tsx:

"use client"
...
  const [isClient, setIsClient] = useState(false);
  useEffect(() => {
    setIsClient(true);
  }, []);
  if (!isClient) return null;
