📣 Summary

Add implementation of get_output_fields() and transform_data_for_output() in QualAction.

📖 Description

This update enables qualitative analysis results to appear correctly in exports or the table view.
The new logic:

• Defines the output fields for each qualitative question (including labels, types, and choices).
• Converts stored qualitative results into export-ready values, including expanding choice UUIDs into readable label objects.

👀 Preview steps

• Run the updated unit tests for QualAction.
• Tests cover both get_output_fields() and transform_data_for_output() to confirm correct behavior.
