Evaluation UI: UX Inconsistency

Is your feature request related to a problem?

When uploading a new dataset, users provide a CSV with question and answer columns. These become the golden dataset's question and
ground truth.

However, in evaluation results, we display columns: question, answer, and ground_truth — where answer is now the
generated response while question and ground_truth are from the original upload. This naming inconsistency creates confusion from a UX
perspective.

Describe the solution you'd like

• Rename the CSV upload columns to question and ground_truth (instead of question and answer)
• This aligns the upload schema with the evaluation results display
• Consistent naming: question = input, ground_truth = expected answer, answer = generated response

Alternative

Keep upload columns as-is but rename ground_truth column in evaluation results UI to expected_answer to differentiate it more clearly
from answer (generated response).

Start by tracing the CSV upload flow and the evaluation results UI to find where the column names are defined. Review the linked pull request and confirm which naming choice was implemented; done means the upload schema and results display use clear, consistent names for question, ground truth, and generated answer.
