[UI/UX 问题] iOS 端键盘液态玻璃效果因底层背景变黑
环境信息：
设备： iPhone 17 标准版
系统版本： iOS 26.5.2
App 版本： v1.21.1
问题描述：
当呼出键盘时，键盘的液态玻璃（毛玻璃）特效会变得部分发黑。这似乎是因为键盘下方的底层视图（Background/SuperView）被渲染成了纯黑色，或者安全区域层级处理不当，导致 iOS 系统的键盘透光效果失效，视觉上像是一块灰黑色键盘。而且，卸载重装也无法解决。
预期行为：
键盘应保持正常的半透明玻璃通透感，能透出聊天界面的背景色，而不是变成灰黑色。

[UI/UX Bug] Keyboard glass effect becomes dark/grayish due to background layer issue on iOS
Environment:
Device: iPhone 17 (Standard)
OS: iOS 26.5.2
App Version: v1.21.1
Description:
When the keyboard pops up, the liquid glass effect (blur effect) becomes partially dark and murky. It seems the background/layer behind the keyboard (Background/SuperView) is rendered in pure black, or the safe area layout z-index is incorrectly handled. This causes the iOS system keyboard's transparency effect to fail, making it look visually like a solid grayish-black keyboard block.Furthermore, uninstalling and reinstalling the app does not resolve the issue.
Expected Behavior:
The keyboard should maintain its standard semi-transparent glass translucency, reflecting the actual background colors of the chat interface instead of turning grayish-black.
