feat(10-01): parameterize DraggableToken and add four new palette tokens

- Add PALETTE_TOKENS array with 5 typed tokens (Signature/blue, Initials/purple, Checkbox/green, Date/amber, Text/slate)
- Update DraggableToken to accept id, label, color props with per-type styling
- Change isDraggingToken from boolean to string | null to track active token id
- Update onDragStart to record active.id instead of just true
- Replace single static token with PALETTE_TOKENS.map() in palette JSX
- Update DragOverlay ghost to show correct label, color, and checkbox-appropriate dimensions (24x24 vs 144x36)
