refactor: streamline connector management UI and enhance document handling

- Updated the ConnectorIndicator component to accurately reflect active connectors and their document counts.
- Improved the display of standalone document types in the ActiveConnectorsTab, allowing users to view all documents easily.
- Enhanced the ConnectorCard to show last indexed dates and formatted document counts for better clarity.
- Adjusted tooltip and aria-labels for accessibility and consistency across attachment upload components.
- Preserved newlines in URL input for webcrawler configuration to ensure proper backend handling.
