Classroom Screen Overlay #221
Description
Allow teachers to display a fullscreen overlay for impromptu classroom screens (e.g. to show a list of current tasks, start / end time for the exam, etc.). Ideally, they could prepare and save multiple screens (e.g. one per class).

MVP idea: Fullscreen overlay containing an Excalidraw canvas, with a hidable "navbar" to switch, add, delete and rename screens.
