test: 前后端对齐—容器复跑验证+清理僵尸测试

- test_main: FastAPI 0.139 _IncludedRouter 不再 flatten，改用 TestClient 探测路由
- datareader: 文件名(sh600000_daily)/patch target(vnpy.trader.database) 对齐 lazy import 实现
- alpha_lab/analyzer/data_adapter: vnpy.alpha/alphalens 容器专用本地 skip
- 删 4 个测废弃 sanguo_web 的僵尸测试（-1267 行死代码）
- pytest.ini: asyncio_mode=auto
- frontend: package.json 加 test script（npm test 可跑）
- NAS 容器 309 passed 全绿验证（Python 3.10，本机 303+6skip）
