侧滑栏精简

### 具体功能需要/Specific features require

侧滑拦精简里“开通会员”和“财富小金库”精简后，如果这两个里面有信息(广告推销)，会产生小红点，由于被屏蔽了，所以说在侧边栏那边没有很正常，但在主页面时，左上角的个人头像会有小红点提醒，希望在屏蔽的时候能同时屏蔽掉信息。
同时对强迫症有点不友好。

Start by locating the implementation of the side-panel simplification and the personal-avatar notification-dot handling. Reproduce the case with “开通会员” and “财富小金库” hidden while their messages generate a red dot, then trace how the hidden items and the main-page indicator are updated. Done means those hidden items no longer produce the corresponding visible notification when simplification is enabled.
