fix(notification): clear auto-dismiss timer on component destroy

onMount scheduled a setTimeout to auto-dismiss the notification after
notification.duration ms but never stored the handle. If the component
was destroyed before the timer fired (parent unmount, navigation), the
timer still ran and called remove() on a stale closure.

Capture the timer id and clear it from the onMount cleanup callback.
