feat(knowledge): implement knowledge item rebuild confirmation dialog and enhance chunk processing options

- Added a confirmation dialog for rebuilding knowledge items in the KnowledgeBase component.
- Introduced new state variables to manage the rebuild process and item selection.
- Enhanced the processChunks function to support question generation options based on configuration.
- Updated the knowledge service to handle question generation settings during document processing.
