feat(usage,pool,codex): 请求详情 body 按需加载、配额选择器重构与 Codex body rules 修正

- usage 详情 API 新增 include_bodies 参数，支持跳过 body 内容返回 has_*_body 标记
- 前端请求详情抽屉首次加载不含 body，切换到 body tab 时延迟加载并展示 skeleton
- Timeline 组件延迟 120ms 挂载，避免阻塞抽屉渲染
- 提取号池配额判断逻辑到 quota-selectors 工具模块并添加单测
- Codex 移除 openai:compact 的默认 body rules 注册
- ModelTestDialog/TestResultDialog 模板格式化
