Refactor and review SwiftUI view files for consistent structure, dependency injection, and Observation usage. Use when asked to clean up a SwiftUI view’s layout/ordering, handle view models safely (non-optional when possible), or standardize how dependencies and @Observable state are initialized and passed.

重构和审查 SwiftUI 视图文件，确保结构一致、依赖注入规范、正确使用 Observation。当需要整理 SwiftUI 视图的布局与顺序、安全处理视图模型（尽可能避免可选类型），或标准化依赖项和 @Observable 状态的初始化与传递方式时使用。
