- Added functionality for row-wise mode calculation (axis=1) to support the Dask DataFrame API. - The new implementation dynamically handles row-wise mode and ensures consistent metadata handling across partitions. - Added validation for the axis parameter, with appropriate error handling for unsupported values. - Ensured compatibility with existing column-wise (axis=0) mode functionality, preserving the original behavior for that case. Resolves dask-expr issue dask#1136.

I conducted a brief search to confirm if this has already been opened here.
Dask Issue #11389 requested the addition of row-wise mode functionality for DataFrames. Through extensive research and testing, I found that the necessary modifications had to be made within dask_expr/_collection.py in the dask-expr repository.
I’m submitting this issue to formally document the need for these changes, and I plan to submit a PR shortly to support this. The code changes are already complete and have been thoroughly tested locally—PR submitted, pending approval.
