refactor(workbench): redesign page cards — rounder corners, unified header, remove DnD

- Increase border-radius to 1.25rem for page cards and add button
- Merge toolbar bar and header into single row (title left, actions right)
- Remove drag-and-drop reorder in favor of arrow buttons
- Make window action icons larger (24px bold) with more spacing
- Title icon monochrome with reduced opacity
- Remove onReorder prop and handleReorder from all carousel consumers
