feat(notifications): sync starred plans to native plugin on star/unstar

Add syncStarredPlansToNativePlugin() and call it from AccountViewView
(schedule + initializeState) and ProjectViewView.toggleStar when New
Activity is enabled so Android prefetch uses the current starred list.

Update notification-from-api-call.md with the helper and file references.
