feat(docker): add SPA static file serving and fix Dockerfile paths\n\n- Add backend/app/main_spa.py with FastAPI static file serving for SPA\n- Fix Dockerfile.traefik to use correct backend path (backend.app.main_spa)\n- Remove web/ references (project has backend/ at root)\n- Frontend dist files served from /app/frontend/dist\n- Health check endpoint at /health\n- Supports Traefik reverse proxy at bttiaw.hzau.edu.cn\n\nCo-Authored-By: Claude <noreply@anthropic.com>
