fix: 点击红点卡片后扣减通知数+不恢复已查看红点

1. NotificationManager新增:
   - acknowledgedCards: 记录已查看的分类
   - cardIncrements: 记录每个分类的新增任务数
   - acknowledgeCard(): 标记分类已查看
   - pendingCount扣除已查看分类的增量

2. HomeFragment:
   - 点击卡片→acknowledgeCard→红点消失+提示条数量减少
   - onResume只恢复未查看分类的红点
   - pendingCount=0时清除所有提示
   - fetchStatistics记录每个分类的增量用于扣减

3. consumeAll重置所有状态(acknowledgedCards+cardIncrements)
