Fix: macOS points not draggable

On macOS 26, interactive dragging could appear “stuck” because the one-shot NSTimer was registered only for the run loop’s default mode. During mouse drags AppKit runs the main run loop in an event-tracking mode, where default-mode timers don’t fire. Register the timer in NSRunLoopCommonModes so it continues firing during tracking and interactive updates keep running.
