Add TODO items for zone editor improvements

New TODO items:
- #15: Show zone dimensions while drawing in graphical editor
- #16: Add ability to move/reposition zones by dragging

Both features will improve the zone editor UX by providing:
- Real-time dimension feedback (pixels and percentages)
- Ability to adjust zone positions without redrawing
- Better visual feedback during zone creation and editing
