Pull request overview

Adds a visible current page indicator to the Catalog pagination UI, and improves perceived responsiveness during URL-driven filter/pagination updates (via React transitions).

Changes:

• Track and expose pageNumber and isPending from useCatalogFilters (using useTransition + session cursor stack length).
• Update CatalogPagination to show “Page N” and add a “First page” button with improved accessible labels.
• Show a ServerListSkeleton while transitions are pending; update unit tests for new labels/props.
