fix: comply with F2E Spec — filename naming, any types, JSDoc

- Rename PascalCase component files to kebab-case (AnnouncementModal →
  announcement-modal, McGlass → mc-glass)
- Replace any types with proper uni-app/WeChat callback types
  (RequestSuccessCallbackResult, LoginRes, ShowModalRes, etc.)
- Add JSDoc documentation comments to all exported/important functions
