feat(dashboard): add commentPreview to ActivityFeedItemDTO; wire via findDataByIds()

Browse Source 
ActivityFeedItemDTO gains a nullable commentPreview field (plain-text, 120 chars max).
DashboardService.getActivity() now calls findDataByIds() once instead of
findAnnotationIdsByIds(), halving DB round-trips for the Chronik page load.
Empty-string previews are normalised to null so the frontend can use ?? cleanly.
