feat(ui): enhance WebSocket event handling and polling logic

- Introduced a new `useEventRecency` hook to track the recency of WebSocket events, allowing for conditional polling based on event activity.
- Updated `AgentInfoPanel` to utilize the new hook, adjusting polling intervals based on WebSocket activity.
- Implemented debounced invalidation for auto mode events to optimize query updates during rapid event streams.
- Added utility functions for managing event recency checks in various query hooks, improving overall responsiveness and reducing unnecessary polling.
- Introduced debounce and throttle utilities for better control over function execution rates.

This enhancement improves the application's performance by reducing polling when real-time updates are available, ensuring a more efficient use of resources.
