• Tests for the changes have been added

📝 Description

🔗 Jira Ticket M2-8092

Fixes responses to the below endpoints consumed by PDP By Participant tab to account for limited accounts possibly having submissions in the database done on their behalf via Take Now:

• GET /activities/applet/{applet_id}/respondent/{subject_id}
• GET /subjects/respondent/{subject_id}/activity-or-flow/{activity_or_flow_id}

🪤 Peer Testing

1. Connect your Admin App connected to this branch of the BE
2. Create an applet with an activity and/or flow, and add a limited account from the Participants tab.
3. For any activity or flow, perform Take Now, providing the limited account for the Who will be providing the responses? dropdown, and any participants for the Who will be inputting the responses? and Who are the responses about? dropdowns.
4. Complete the assessment in the Web App so that there is at least one submission by the limited account as the respondent.
5. In the Admin App, use DevTools to figure out the applet ID, subject ID of the limited account, and the activity/flow ID of the activity/flow for which you performed take now.
6. Open your local Swagger UI and authenticate your session as an admin account.
7. From the Swagger UI, call these endpoints providing the above IDs:
   • GET /activities/applet/{applet_id}/respondent/{subject_id}
   • GET /subjects/respondent/{subject_id}/activity-or-flow/{activity_or_flow_id}
     Expected outcome: Each endpoint succeeds with a valid response, and each resulting array contains at least one entry.
