Review and submit button should be placed at different positions

Currently the review and submit button doesn't serve a real purpose since they're in the same position, so it's really often that the prompter would misclick twice on the button and realize later that they want to change their submissions. These buttons should be placed either at different positions or have a time delay before you're able to click on the submit button, or both.

No file, test, or entry point is named in the issue. Start by locating the review and submit controls in the frontend, then determine which placement or delay best prevents accidental submission; done means the controls cannot be misclicked in sequence and the behavior is covered by the relevant UI checks.
