Replace Username with Name in Winner Banner #73

Currently, the winner banner displays the user's username. We want to improve the UI by showing the user's full name instead, while keeping the username as a fallback in case the name is not available.

Required Changes:

Navigate to:
result-dashboard.tsx
Go to line 116

Replace:

winner.username

With:

winner.name || winner.username

Expected Behavior:

If winner.name exists → display the full name
If winner.name is missing/null → fallback to winner.username
