feat(knowledgeBase): enhance dataset creation with progress tracking and model defaults

- Add Progress component import to display file upload progress in real-time
- Implement progress bar rendering for files with 0-1 progress values (processing state)
- Refactor progress column logic to handle three states: completed (1), processing (0-1), and pending (0)
- Add automatic default model selection for each type when creating new knowledge base
- Improve file removal handling with better error messages and conditional server deletion
- Add console logging for upload cancellation and file deletion operations
- Remove loading state from primary button to prevent UI conflicts
- Comment out Spin wrapper on step 2 to allow better progress visibility
- Update Chinese translation for total_running_apps label for clarity
- Enhance error handling with i18n support for deletion failures
