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).

Empieza siguiendo el flujo de carga de CSV y la UI de resultados de evaluación para encontrar dónde se definen los nombres de las columnas. Revisa el pull request vinculado y confirma qué opción de nomenclatura se implementó; se considera terminado cuando el esquema de carga y la visualización de resultados usan nombres claros y coherentes para la pregunta, la Ground Truth y la respuesta generada.
