fix(web): sync finding traffic bindings between overview and reproduction steps

Align finding detail reproduction with AntiFox: store reproduction JSONB
(entry_point/prerequisites/steps/provenance), bind traffic via step_index,
syntax-highlight HTTP in steps/traffic panel, fall back to legacy evidence
when reproduction is absent. Old findings are not backfilled.

+
+### 任务情报
+
+在「系统配置 → 任务情报」开启 **Agent 自动记录**，即可在任务详情的「任务情报」中集中查看凭据、重要线索和敏感数据。此开关默认关闭；关闭时不向 Agent 注入情报工具、附加字段或提示，不启动额外总结 Agent，已有记录仍可查看。开启会增加提示及上报的 Token 消耗，对后续 Agent 执行生效；已在运行的会话可能仍保留旧工具描述，关闭后服务端立即拒绝新增情报。
+
+Worker 可调用 `record_intelligence`，或在 `record_fact` 的单条/批量事实中附带 `intelligence` 数组一起提交。`insert_assets` 本次提交的服务 `auth` 自动登记为未验证凭据，避免重复上报。任务、执行节点由系统绑定，记录需要真实来源证据；获取凭据不等于登录成功。
+
+页面支持分类、标题/上报者搜索、状态筛选、分页、状态更新及来源查看。凭据、敏感数据的正文和来源证据直接展示在列表及详情中，无需额外点击显示。直接关联任务的记录标明继承且只读；在资产页选择一项资产后点击「关联情报」可查看同一份记录。情报随任务归档、恢复和删除；新版归档格式为 v4，仍支持读取 v1–v3。此功能不自动补提取历史会话。
