refactor: remove PageLayout from all frontend pages, delegate to FrontendLayout

- Remove PageLayout wrapper from Home, HomePage, Archives, Tags,
  TagDetail, PostDetail, Search, and About components
- Remove unused imports: use_nav_items, use_route, PageLayout, Route
- Pages now render only their content; Header/Footer are provided by
  FrontendLayout via the router's #[layout] attribute
- Skeleton screens (DelayedSkeleton) remain in data-loading branches
- This eliminates redundant Header/Footer re-mounting on every route
  change, which was the primary source of page transition flicker

Files changed:
- src/pages/home.rs: remove PageLayout, keep HomeInfo + HomePosts
- src/pages/about.rs: remove PageLayout, render content directly
- src/pages/archives.rs: remove PageLayout, keep header + ArchivesContent
- src/pages/post_detail.rs: remove PageLayout, keep PostDetailContent
- src/pages/search.rs: remove PageLayout, keep search form + results
- src/pages/tags.rs: remove PageLayout from Tags and TagDetail
