Replaces custom expand/collapse with Collapsible

Migrates ScheduledEventCard to use the Collapsible component from the UI library.

This simplifies the component's structure and improves accessibility by leveraging the built-in features of the Collapsible component.
Removes custom logic for managing the expanded/collapsed state.
