refactor: use DeprecationWarning instead of logger.warning

[vdusek]

Summary

• Replace logger.warning() with warnings.warn(DeprecationWarning) for deprecated params in batch_add_requests() (both sync and async) to match the pattern used in DatasetClient.download_items()
• DeprecationWarning is the Python standard — visible by default, caught by pytest -W error::DeprecationWarning, and filterable via warnings.filterwarnings()
• Remove unused logging import
