1. 首页数据不刷新 — JournalRepository 添加 onJournalChanged
   Stream 变更通知,HomeBloc 订阅后自动刷新
2. 画笔再次点击不弹出面板 — 添加 ToolReactivated 事件,
   工具栏检测已激活工具时发出重新激活信号
3. 钢笔铅笔效果一样 — 调整 perfect_freehand 参数
   (pen: size 10/smooth 0.65, pencil: size 3/smooth 0.35)
4. 橡皮擦不生效 — ActiveStrokePainter 橡皮擦模式绘制
   半透明灰色反馈,笔画完成后 setState 触发 Layer 1 重绘
5. 贴纸文字无法缩放 — DraggableElement 用 Scale 手势
   替换 Pan 手势,支持双指缩放和旋转
