test: add comprehensive tests for datasets components with 95%+ coverage

- Add tests for api-access/index.tsx (100% coverage)
- Enhance tests for operations.tsx (95.65% coverage)
- Enhance tests for status-item/index.tsx (93.75% coverage)
- Add tests for simple components: chunk, loading, preview, statistics, empty-folder, no-linked-apps-panel, api/index
- Remove tests for complex component retrieval-param-config
- Test operations: archive, unarchive, enable, disable, sync, pause, resume, delete, download, rename
- Test switch toggles with debounce handling
- Test error notifications and success callbacks
