feat(flow): 链路图时间轴出口(W1)—— 所有轮次按时间正序

- 新增 GET /api/v1/admin/flow/timeline?sessionId=&limit=&before=:时间正序多轮,
  每轮 {turnId,round,startedAt,endedAt,lanes[]};limit 缺省 50/上限 200 + before 游标
- 数据源=落盘 flow_graphs + 内存最近一轮(同图 id 去重);保留期 168h 外的轮次不返回,
  但响应给 retentionHours/retentionEnabled/truncated ⇒ 前端如实标注,不悄悄少一块
- 老出口 GET /admin/flow/graph 零 diff;角色门 writeAuth(owner|admin)
- 4 个变异自检(游标 <= 重复、分组降级、去重缺失、truncated 静默)

// 本文件钉住契约 v0.80 的新出口 `GET /api/v1/admin/flow/timeline`(design/19 §7;切片 W1)——
// 主人 2026-10-06 的原话:「web 后台的全链路流程图我要的是所有消息按时间顺序串起来的流程图,
// 而不是只有最新一个来回」。
//
// 走真路径(真发布器 + 真 SQLite + 真迁移 0022/0023 + 真 HTTP handler),断言的是**线上
// 形状**与**库里的事实**:多轮按时间正序、一轮含该轮每一路、`before` 游标翻页不重不漏、
// 内存里在飞的那一轮并进同一轮且不重复、保留期两个字段如实、未接线时 500 flow_unavailable。
