Fix PWA cache preventing deployment updates from loading

[Copilot]

Deployed updates weren't loading—users saw old cached versions instead of new code. Browser-level HTTP caching of index.html prevented the service worker from detecting updates.

Changes

Added cache control meta tags to index.html:

<meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate">
<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Expires" content="0">

This forces browsers to revalidate index.html on every load, allowing the Flutter service worker's update mechanism (skipWaiting + onlineFirst) to function correctly.

quand je deploie le code c est lancien qui ouvre pas les nouveaux mise a jours

I cannot deploy to Vercel directly as I don't have access to deployment credentials. However, the changes are ready for you to deploy.

When you deploy this to Vercel, the cache control meta tags in index.html will prevent browsers from caching the HTML file, ensuring users always get the latest version. You can verify it's working by:

1. Deploy to Vercel
2. Open browser DevTools (F12) → Network tab
3. Refresh the page and check the index.html request headers
4. You should see Cache-Control: no-cache, no-store, must-revalidate in the response headers

The changes in commit f1df32d are ready to test.
