fix(websocket): Add explicit HTTPS origin for WebSocket CORS

- Add setAllowedOrigins() to explicitly allow HTTPS connections
- Fixes Mixed Content error when connecting from HTTPS frontend
- Allow https://www.team11.giwon11292.com (production)
- Allow http://localhost:3000 (development)
- Add detailed STOMP connection logging for debugging
