fix: display notebook icons correctly instead of icon names

Fixes issue where notebook dropdown showed icon name (e.g., "folder")
instead of the actual icon component.

Problem:
- note-card.tsx was displaying {notebook.icon} as text
- Users saw "folder", "book", etc. instead of icons

Solution:
- Import Lucide icon components (Folder, Book, Briefcase, etc.)
- Add ICON_MAP matching icon names to components
- Use getNotebookIcon() function to resolve icon name to component
- Render component as <NotebookIcon className="h-4 w-4 mr-2" />

Changes:
- components/note-card.tsx:
  - Add LucideIcon and icon imports
  - Add ICON_MAP and getNotebookIcon() helper
  - Update notebook dropdown to render icon components

Result:
✓ Notebook icons now display correctly in dropdown menu
✓ Consistent with notebooks-list.tsx implementation
