📝 Description

This PR adds the ability for a prolific recruit to submit their answer for an activity. So far for this to be working, the applet has to be configured with a public link, and needs to contain only one activity.

How it works: Prolific participant is redirected to mindlogger public link. The app parses the URL and searches for 3 parameters: PROLIFIC_PID, SESSION_ID & STUDY_ID.

At this point 3 checks are made:

• (Frontend check) One of the parameter is missing => ERROR
• (Backend check) The prolific integration is not configured in the backend => ERROR
• (Backend check) The study_id is wrong => ERROR

If all checks passed: We store the parameters in redux and the user can take on the activity. If the user has already submitted their answer, they will be blocked and cannot take on the activity

On submission, we send the prolific parameters to the backend:

• if the submission has been validated by the backend, we then make a query for the completion codes and redirect to prolific
• if an error occurs in retrieving the completion code we show an error banner asking the participant to follow the NOCODE policy.
• if the participant has already completed the activity/applet, an error occurs and we don't redirect the user.
