Bug: JSON.parse on localStorage user data without try-catch crashes the app

[Siddh2024]

Summary

In Client/src/App.jsx, JSON.parse(localStorage.getItem("user") || "{}") has no try-catch. Corrupted localStorage data crashes the entire React app on every route.

Details

• File: Client/src/App.jsx
• No error handling around localStorage deserialization
• Corrupted data (e.g., from a previous app version) throws an uncaught exception
• Also affects: token stored in localStorage instead of httpOnly cookies

Impact

Any localStorage corruption causes a complete app crash with no recovery. Users may need to manually clear site data to fix it.

Suggested Fix

Wrap in try-catch, default to null on failure, and clear corrupted entries automatically.
