feat(label-file-binding): add batch creation and improve label ID handling

- Introduced `CreateLabelFileBinDingBatch` API for batch label binding.
- Added `collectLabelIDs` helper function to handle label ID parsing.
- Enhanced label ID handling to support varied delimiters and input formats.
- Refactored `CreateLabelFileBinDing` logic for improved code readability.
- Updated router to include `POST /label_file_binding/create_batch`.
