feat: add discard all functionality to ideation view

- Introduced a new button in the IdeationHeader for discarding all ideas when in dashboard mode.
- Implemented state management for discard readiness and count in IdeationView.
- Added confirmation dialog for discarding ideas in IdeationDashboard.
- Enhanced bulk action readiness checks to include discard operations.

This update improves user experience by allowing bulk discarding of ideas with confirmation, ensuring actions are intentional.
