What does this implement/fix?
This PR adds regression tests ensuring that
DataFrame.interpolate(method="time")works correctly with nullableInt64andFloat64dtypes.The original issue (#40252) reported that
interpolate(method="time")raised a ValueError for these dtypes. On currentmain, the behavior is correct, but no dedicated tests existed. These tests safeguard against future regressions.Changes

No user-facing API change. Strictly test coverage.
