Pandas 3.0 uses shorter class names (e.g., `pandas.DataFrame` instead of `pandas.core.frame.DataFrame`). This adds S3 method registrations and class checks for the new names while maintaining backwards compatibility with older pandas versions. Also fixes string column conversion for pandas 3.0 which no longer accepts the second argument in the StringArray constructor. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

This used to reference the copy argument, which defaults to False and became a keyword argument in v3. We can simply not pass it
