add favourites to new dashboard

[Mbeaulne]

Description

Added a new FavoritesSection component that displays user favorites with search and pagination functionality. The component shows favorite pipelines and runs as clickable chips with different styling, includes a search input to filter by name or ID, and supports pagination for large lists. Connected this component to the dashboard favorites route, replacing the placeholder "Coming Soon" page.

Additional Comments

The component integrates with the existing useFavorites hook and uses consistent UI components from the design system. Pipeline favorites are styled with violet colors while run favorites use emerald colors for visual distinction.

Reviewer note: FavoritesSection.tsx re-added here is identical to the version deleted in #1996 — it is deleted again one PR later in #1998 when the design switches from chips to cards.

DashboardFavoritesView.tsx introduced here as a 5-line shell is completely rewritten in #1998. You can treat this PR as a brief stepping stone — the final favorites implementation is in #1998.
