chore(cleanup): delete unrouted legacy pages, update docs

pages/category, pages/search, pages/item-detail, pages/info/**,
pages/legal/** (40+ files) were entirely unrouted dead code:
- category/:id, category/:id/items, search all redirect/route to
  CatalogContainerComponent
- product/:id routes to ProductDetailsContainerComponent, not item-detail
- cmsContentRoutes (meant to route info/legal) is a literal empty array;
  static/legal content is served by the CMS-driven :staticPath ->
  StaticPageComponent route instead

dynamic-renderer/ is unrelated and stays - confirmed active, it's the
live homepage rendering pipeline (HomeComponent -> WebsiteRuntimeFacade
-> PageRendererService/PageResolverService -> DynamicPageLayoutComponent).

Updated docs/TODO.md, docs/KNOWN-ISSUES.md, docs/FRONTEND-ROADMAP.md,
docs/PROJECT_INDEX.md to reflect the resolution.
