feat: refactor document fetching and improve comment batching

- Replaced the useDocuments hook with React Query for better caching and deduplication of document requests.
- Updated the ConnectorIndicator component to fetch document type counts using a new atom for real-time updates.
- Enhanced the useComments hook to manage batch requests more effectively, reducing race conditions and improving performance.
- Set default query options in the query client to optimize stale time and refetch behavior.
