ED.2 Live TeamWork: class view, the teacher looks in on each student's work

Owner 2026-11-03 (educator kit): "allow instructor to look at student progress". Built as the people list in Live TeamWork (same module, assets/js/live-follow.js): everyone in the session with their colour and name, the tool they are running, the sheet they are on, how many edits this window saw from them and when the last one was, and a Follow button on each, so the teacher can go to a student's view. Names from other people reach the page as text only. NOT built from the first plan: students each working in their own drawing inside a class room, a live thumbnail of each student's work, and "Look in" read-only or "Help" with a separate viewer role. Today the class works in one shared drawing and the teacher sees the class at a glance in the list. Not tried in a live session with real students.
