- Implemented WebSocket-based ban notifications to WorkAdventure
- Banned users are now immediately kicked from the world
- Created notifyWorkAdventureBan utility function
- Integrated with existing ban creation endpoint
- Graceful fallback: ban still takes effect on next login if notification fails
- Non-blocking operation: ban creation succeeds even if real-time kick fails
- Added WORKADVENTURE_PUSHER_URL and ADMIN_SOCKETS_TOKEN environment variables
- Updated documentation with configuration instructions
