refactor: 深度重构任务预设编辑器 UI 布局

步骤 1: TASK_PROFILE_TABS 调序（生成参数→Prompt 编排→正则）
步骤 2: 预设头部卡片从 2 列 grid 改为堆叠 flex
  - 操作按钮分组（保存|导入导出|恢复默认）+ 分隔符
  - 恢复默认按钮 danger 样式
步骤 3: 生成参数 Tab 从 2 列卡片 grid 改为单列堆叠
  - 运行时说明改轻量 note 样式
步骤 4: Prompt 编排工具栏重组
  - 新增块按钮统一行内 + 分隔符
  - 简化内置块选项文字
  - 增加块数量显示
步骤 5: 正则 Tab 从 3 列 grid 改为 2 行响应式布局
  - 上方：复用配置 + 规则列表（2 列）
  - 下方：规则编辑器（全宽）
  - 应用阶段拆分为输入/输出两组
