feat: V1记忆系统支持、管理员记忆编辑及对话记忆注入开关

- 新增 V1 记忆系统（memory.json）支持：提取结果强制中文、历史字段修复为增量累积日志
- 用户设置页面：V1 模式下新增 agent 选择器，可查看各 agent 的私有记忆
- 管理员记忆页面：区分 V1/V2 渲染，V1 支持完整 CRUD（用户画像/历史摘要/事实记录）
- 后端新增 V1 记忆 CRUD API（sections/facts），前端同步添加对应 hooks 和 API 调用
- 新建专家页面：标记 bootstrap 线程类型，跳过记忆保存，侧边栏过滤该类线程
- 输入框工具栏新增「记忆」开关：关闭时 V1/V2 均不注入，开启时按 config.yaml 版本正常注入
- 修复 agent 目录不存在时的 FileNotFoundError，回退至默认配置
