feat(rag): 接入 rag 知识库模块 + uapi 外部 API 网关

- app/pipeline_app.py: load_uapi() + init_rag_module()（uapi 必须先于 rag）
- build.sh: 四处模块列表加 uapi/rag（clone/pip/xls2ui/wwwroot symlink）
  新增 8b 步骤：json2ddl 建 rag_* 表 + 导入 uapi_seed.sql 配置种子
- wwwroot/index.ui: 侧边栏加「知识库」菜单项(open_tab 符合 UI 导航契约)
- i18n zh/en/jp/ko: 补知识库相关四语言文案

rag 表统一 rag_ 前缀，与产线业务表隔离；数据独立于 ragserver
