Fix test notification system

- Remove duplicate NotificationService.start() call from VibeTunnelApp
- Fix compression middleware blocking SSE events by excluding /api/events
- Add Accept-Encoding: identity header to EventSource to prevent compression
- Add comprehensive debugging to EventSource for data reception
- Fix Swift compilation errors with explicit self references
- The issue was that SSE events were being gzip compressed, preventing proper streaming
