feat(knowledgeBase): add knowledge graph rebuild and delete functionality

- Add deleteKnowledgeGraph and rebuildKnowledgeGraph API endpoints to knowledgeBase.ts
- Add internationalization strings for rebuild confirmation dialog and success/failure messages in both English and Chinese
- Implement rebuild mode logic in CreateModal component with confirmation dialog before rebuilding
- Add originalType state tracking to distinguish between rebuild and regular edit modes
- Update handleSave to trigger graph deletion and rebuild when in rebuild mode with graphrag enabled
- Add handleDeleteGraph method to delete existing knowledge graph data before rebuild
- Update performSave to use correct type value during save operation in rebuild mode
- Enhance Private.tsx to refresh knowledge base details after table data refresh
- Import new API functions (deleteKnowledgeGraph, rebuildKnowledgeGraph) in CreateModal
- Update KnowledgeGraphCard component timestamp in file header
