Fix 2D control panel positioning relative to canvas

- Fix panel positioning calculation to account for panel height
- Position panel bottom edge 10% from canvas bottom (not container)
- Ensure panel stays within canvas bounds when WebGL canvas is active
- Update positioning on window resize for responsive behavior
- Resolves issue where panel appeared partially below canvas
