feat(knowledgeBase): enhance file upload and dataset creation with abort support and improved UX

- Add AbortSignal support to uploadFile API for cancellable uploads
- Implement custom onRemove callback in UploadFiles component with confirmation dialog
- Add i18n translations for file removal confirmation and error messages
- Update supported file types documentation to include IMAGE and MEDIA formats
- Improve file removal UI with cursor pointer styling
- Refactor getModelList API to remove unused type parameter
- Add Form import and UploadFile type for better type safety in CreateDataset
- Enhance error handling and user feedback for file operations
