feat dashboard latout

[Mbeaulne]

Description

Refactored the dashboard from a single page to a multi-page layout with sidebar navigation. Removed the old FavoritesSection and RecentlyViewedSection components and replaced the single Dashboard component with a new DashboardLayout that includes a sidebar with navigation to different dashboard sections (Runs, Pipelines, Components, Favorites, Recently Viewed). Added placeholder routes for each section that will be implemented in subsequent PRs. Made RecentlyViewedItem and RecentlyViewedType interfaces private to the useRecentlyViewed hook. Updated knip configuration to remove unused ignore patterns.

Reviewer note: This is the major architectural pivot in the stack. Key things to know:

• Dashboard.tsx, FavoritesSection.tsx, and RecentlyViewedSection.tsx are all deleted here — this is intentional, replacing the flat page with a sidebar multi-route layout.
• DashboardLayout.tsx introduced here is the right thing to review, but be aware it is further modified in Updates runs and pipelines designs #2003, add new section to the side bar #2004, moves app footer #2010, and Add dashboard home view with favorites, recently viewed, and my runs sections #2011 (four consecutive PRs refine the sidebar chrome). The version here is not the final form.
• All sub-routes (/runs, /pipelines, /components, /favorites, /recently-viewed) point to ComingSoon = () => null stubs — these are filled in by subsequent PRs.
• The index route redirects to /runs here but is changed to render DashboardHomeView in Add dashboard home view with favorites, recently viewed, and my runs sections #2011.
