FFQ Editing Capabilities

Several participants have reached out to the help account because they took breaks while completing the FFQ and their session timed out after a period of inactivity. When this happens FFQ is closed and mark as complete, regardless of the level of completion.

1. We should add text in the participant interface indicating that the session will time out at 90min, so FFQ should be completed in one session.
2. Can a feature be included in the website where participants can go back to edit/complete the FFQ. I believe Viocare supports the ability to save and return without submitting, at least for their website survey.

Start by tracing the participant-facing FFQ flow and the 90-minute inactivity timeout, then identify where completion is recorded. The issue names no files or tests, so first map the website entry points and determine how save-and-return would interact with completion; done means timeout guidance is visible and participants can edit or complete an unfinished FFQ before submission.
