refactor: share the sway helpers
classroom-dvd-session needs to ask sway whether VLC has taken the screen, which is the same tree walking classroom-window already does. One copy, in a module both import; classroom-window loses a third of its length. The state machine is worth protecting through a move like that, so its regression test comes with it: the exact swaymsg commands for launch, focus, minimise, restore, Super+M, Super+Shift+M, the scratchpad rescue and sway not running at all.
