Revert the temporary placeholder values back to proper authentication
context usage. This restores:
- Real username from auth context instead of 'something'
- Real user avatar from auth context instead of 'something'
- Proper auth import that was accidentally removed
This ensures users see their actual GitHub username and avatar
in the game interface and maintains proper security context.
Temporarily revert to hardcoded user data instead of auth context
values. This appears to be debugging/development code that should
be reverted back to proper authentication context usage before
production deployment.
Note: This should be changed back to use actual auth context values.
Add empty Messages function in chat.go as foundation for future
real-time chat functionality. Currently a no-op but provides the
basic handler structure needed for WebSocket chat integration.
