Synchronize shell material presentation with surface commits

Queue popup, modal and notification material geometry and opacity until the matching content buffer commits. Remove event-handler opacity writes that could present material state ahead of content, while preserving compositor dismissal ownership.

Add pending-presentation regression coverage and update the nested shell lifecycle check.
