fix: resolve detail page auto-dismissal caused by nested navigation

The navigation issue where detail pages would immediately close after
opening was caused by nested navigation containers:

- NavigationStack at root conflicting with NavigationView in .navigatable()
- Nested NavigationLinks inside FeedItemView and RecentItemView
- NavBarModifier wrapping content in additional NavigationView

Changes:
- Use NavigationStack in MainPage instead of NavigationView
- Remove .navigatable() calls from detail pages (FeedDetailPage,
  MyFavoritePage, UserDetailPage, TagDetailPage)
- Remove nested NavigationLinks from FeedItemView and RecentItemView
- Simplify NavbarHostView by removing nested NavigationView
- Add UI test to verify navigation stays open
