fix: 前端消息拆分+动作消息样式+DevTools自主思考状态保持+记忆表名修复

- 侧边栏底部 "昔涟 AI" 改为 "昔涟"
- 暂时禁用消息朗读按钮
- 修复前端 response 处理器：支持 gateway 发送的 content+role+msg_type 字段，
  使动作消息(括号内容)正确拆分为独立的 ActionMessageBubble 显示
- 修复 DevTools 自主思考面板：5秒自动刷新后展开的思考日志不再自动折叠
- 修复 memory-service 表名不一致：memory_entries → memories，
  解决 DevTools 记忆管理页面查不到 admin 用户记忆的问题
- 修复 sessionStore 解析历史消息时 msgType 未定义引用
