+Updates the content editor's Publish section so authors can distinguish the live version from draft changes and choose immediate or scheduled publishing from one contextual action menu.

+Publishing dates and schedules display in the browser's local time zone while stored timestamp values remain unchanged.
+
+Schedule and unschedule responses now return the current revision token so subsequent editor saves retain optimistic-concurrency protection.
