feat: 任务工作区可配置跳转按钮(按钮管理) + 底部快捷跳转栏 + 目的树收起/空自动问答

- 新增「按钮管理」admin 页(/admin/task-buttons)：按业务(rwfx/3qfx/xdfx)配置跳转按钮，
  支持改名称/类型(外链·切换业务·目的树弹框)/目标/追加参数名(id·task_id)/任务id·行动id/启停/排序
- 跳转按钮从左侧栏移到工作区底部「快捷跳转」栏：红底白字、靠右、变大；rwfx 历史 4 按钮纳入配置
- 后端新增全局共享 store /api/task-buttons (table task_buttons，admin 整体替换)
- xdfx 行动id/任务id：登录暂存原始行动id，按钮可选追加任一；id 参数名可自定义
- rwfx 清除记录移到「新建对话」下、去掉任务操作框；查询任务目的为空时自动发第一次问答
- 目的树面板默认收起；「弹框查看」抽成可复用 TaskPurposeDialog，可作为按钮配置到任意页面
- 文档(根/后端 CLAUDE.md) + 后端测试 tests/test_task_buttons.py
