Phase 3: Pass authentication token to SignalR connection URL

- Modified main.js to pass authToken to SignalRBridge constructor
- Updated signalr-bridge.js to append token to hub URL
- Removed skip logic for negotiate endpoint in middleware
- SignalR negotiate request now includes token for authentication
- Cookie is set after successful negotiate for subsequent requests

This enables SignalR connections to authenticate using the same
token-based mechanism as HTTP requests, completing the authentication
flow for both Blazor pages and SignalR hub communication.
