Canvas peer review: use To Do link, not the Assignments index

In Canvas courses that hide the Assignments tab, /courses/<id>/assignments redirects to the course home. The actual peer review lives on the parent assignment's page with a ?reviewee_id=<n> query (the 'Peer Review, <assignment>' item in the course home To Do sidebar links straight to it), not on any separately named 'Peer Review' assignment, which may be just an instructions page. With Claude in Chrome, find() refs can lag a navigation and point at the previous page's DOM, so call find again after the page settles before clicking. Saving the peer review rubric counts as submitting it, so open the page and leave the scoring to the student.
