feat: split honeypot and dashboard into separate services on dedicated ports

- Honeypot listens on port 5010
- Dashboard listens on port 5123 at URL /
- Add app_dashboard.py as standalone FastAPI app
- Add start.sh to launch both uvicorn processes
- Fix dashboard_path computation to return "" at root (avoid double-slash URLs)
- Update Dockerfile, docker-compose.yaml, config.yaml, config.py
