feat(ui): 报告中心改行式列表，阅读页并入外壳并把目录挪到右侧常驻

报告中心原来是卡片方阵，状态只靠三块底色区分；报告一多，扫读成本
按卡片数线性涨。现在一列一行：带色点的状态 chip、标题、创建时间 ·
深度 · 主题，操作靠右。失败原因从右边一小块挪进行内，能完整读到。

chip 里原来的 StatusIcon（generating 转圈、ready 打勾、failed 警告）
换成 5px 色点——原型如此，且列表是轮询不是演出。失败行不加「重新
生成」，顶栏已经有唯一的生成入口。

行内小字只写接口真给的东西。GET /api/reports 不返回节数和盘数，所以
不写「9 节 · 22 张盘」（VOICE.md 第 2 条），原型图上那行是 mock。

/reports/[reportId] 是最后一个脱离外壳的全屏路由，九个 phase 全部并进
SecondaryShell，根节点从 <main> 改成 <div>（外壳自己就是 main）。

任务书 E10「没有目录」已过期：目录在 cfcd369d 就存在。本轮把它从左栏
挪到正文右侧并定稿视觉，位置用 grid-column 显式指定而不是靠 DOM 次序，
这样窄屏抽屉仍能排在源码最前面，不会掉到全文末尾。860px 以下常驻栏
消失、折叠抽屉保留——删掉抽屉等于窄屏彻底失去章节定位。

挂外壳带出一个真实风险：window.print() 打的是整篇，而 .chat-app /
.chat-panel 是 height:100%;overflow:hidden，会把九节报告裁成一页。阅读
页因此多挂一条 media="print" 样式，把外壳既隐藏又解锁。放组件里而不是
globals.css：它只在阅读页挂载期存在，对话页的打印不受影响，也不用
:has() 去够祖先，更不越界到并行轮次的 CSS 区段。

纸面三个 token 一个没动，--report-accent 仍是 #85432f；目录栏用应用
调色板，因为它是 chrome 不是纸。report-chart-grid-rehype.ts 一行未动，
新增断言守住它仍然接线（BUG-616/617）。

tsc 0 错；lint 0 error / 118 warning（未增）；3350→3355 条，0 条既有
断言被改，31 条无 Docker 失败与基线逐条一致；四个路由渲染标记不变，
/ 首屏 gzip −0.58%。

「20 张盘以上不重叠、滚动不卡」与「挂外壳后的打印真实输出」无真机做
不了，已写成环境缺口，清单在 docs/testing/cend-report-20260916.md。
