Show "DEV" badge in navbar on development mode 🛠️
File: client/src/pages/Dashboard.jsx

No way to tell if you're on local dev
or production 💀 fr!!

Fix:
const isDev = import.meta.env.DEV

{isDev && (

DEV

)}

~5 lines! Vite already provides import.meta.env.DEV ✅
No backend needed 🎯
Disappears automatically in production!! 🔥
