无障碍与用户体验：
- 补全 OnboardingView/ProcessingView/ResultView/WallpaperGuideView 无障碍标注
- ContentView 添加后台切换截屏保护（模糊覆盖层）
- EditorView iPad 右侧面板改为响应式宽度（minWidth:320, maxWidth:420）
- ResultView CelebrationParticles 改用 Task 替代 DispatchQueue 延迟
- DesignSystem accessibility key 从中文改为英文
- EditorView/WallpaperGuideView 生成按钮 accentColor 统一为设计系统
- OnboardingView 第四页添加相册权限预告提示

核心库优化：
- LivePhotoLogger 添加日志安全注释
- CacheManager.makeWorkPaths 添加磁盘空间预检查（<500MB 报错）
- ImageFormatConverter BGRA/ARGB 转换改用 vImagePermuteChannels 加速
