Opsai: Fix keyerror in user profile function by adding sa 5837993114159319764

[mw-middleware-labs-sandbox]

Summary of Changes

The fix addresses a KeyError in the user_profile function by implementing safe dictionary access and proper error handling. Instead of crashing when a user is not found, the application will now return an HTTP 404 Not Found response.

Checkpoints:

• Implement Safe Dictionary Access: Changed direct dictionary access user_data[username] to user_data.get(username) to prevent KeyError when a key does not exist.
• Handle User Not Found: Replaced the bare raise statement with a return of jsonify({"error": "User not found"}), 404 to provide a clear error message and appropriate HTTP status code for non-existent users.
