Unify internal monitor detection across scripts

Four scripts matched internal panels with contains("eDP") while
omarchy-monitor-state used test("^(eDP|LVDS|DSI)-"), so laptops with
LVDS or DSI panels were internal to monitor-state but invisible to the
clamshell, mirror, and external-active logic. All five sites now share
the inclusive anchored pattern.
