Add icons to distinguish between feed, story, and combined posts

Integrates new icons for 'feed', 'story', and 'both' post types across CalendarListView, CalendarView, RecentPublications, and History components. Adds a post preview modal and refactors history view to display scheduled posts. Enhances CalendarView with auto-refresh.
