chore: 代码清理（debug日志+孤立文件+未用字段+测试修复）

1. 去掉 fetchStatistics/renderDots 中的 debug Timber.d
2. 删除孤立文件: bg_new_task_hint.xml, bg_btn_primary.xml, bg_btn_secondary.xml
3. 删除未用字段: onPendingCountChanged
4. 单元测试修复:
   - 添加 Dispatchers.setMain/resetMain (JVM无Main线程)
   - 新增: 数字id解析、acknowledgeCard减pendingCount、ack清除、preNotificationStats
   - 总计 22 条测试
