feat(personalization): 将堆叠块显示模式保存到后端 personalization.json

- 新增个人化设置 group_sidebar_by_workspace / sidebar_pinned_workspaces /
  sidebar_workspace_order，支持分组视图、置顶、排序
- 后端 conversation API 支持 workspace_id 参数，用于获取/创建/加载/删除
  指定工作区的对话，避免切换视图时 session 漂移
- server/context.py 新增 update_session 参数，临时解析目标 terminal 时不污染
  当前会话
- 前端 ConversationSidebar 实现分组折叠、运行中指示器、新建/更多操作菜单、
  动画同步
- config/terminal.py 默认 TERMINAL_SANDBOX_MODE 由 docker 改为 host
