feat: Implement infinite scroll for agent grids and enhance performance

- Added `useInfiniteScroll` hook to manage infinite scrolling behavior in agent grids.
- Integrated infinite scroll functionality into `AgentGrid` and `VirtualizedAgentGrid` components.
- Updated `AgentMarketplace` to pass the scroll container to the agent grid components.
- Refactored loading indicators to show a spinner instead of a "Load More" button.
- Created `VirtualizedAgentGrid` component for optimized rendering of agent cards using virtualization.
- Added performance tests for `VirtualizedAgentGrid` to ensure efficient handling of large datasets.
- Updated translations to include new messages for end-of-results scenarios.
