[ameliav]

🗣 Description

CRASM-2531

🧪 Testing

• Ensure all relevant data processing functions in the frontend (e.g., API response handling, state management, and data binding) are updated to parse and work with snake_case attributes.
• Update unit tests to verify that the frontend correctly processes and displays snake_case data.
• Confirm that the updated frontend seamlessly integrates with the Python backend without any errors or data mismatches.
• Ensure the frontend retains functionality with camelCase data in case certain backend modules still deliver data in that format during the transition period.
