Add unit tests for pandas-inherited pd.DataFrame methods with ArkoudaExtensionArray columns #5197
Description
Write unit tests covering pd.DataFrame methods that are inherited/available via pandas when one or more columns are backed by ArkoudaExtensionArray.
The goal is to verify pandas semantics (column-wise ops, alignment, dtype/NA behavior, indexing/selection, reductions, sort/groupby-compat where applicable) and catch regressions in inheritance/dispatch for Arkouda-backed DataFrames, including mixed DataFrames with both Arkouda-backed and NumPy-backed columns.
