Fix debug draw and physics positioning issues

- Fix critical bug in PlanckDebugDraw.js where circles were drawn at body center instead of local positions
- Add DEBUG_DRAW_SENSORS support with orange styling and no outlines
- Fix Chuck's sprite positioning to align with physics body center (pivot adjustments)
- Correct fixture Y coordinates so Chuck stands upright instead of on his head
- Position foot sensor correctly below legs for proper ground detection
- Remove cyan crosses and make yellow center-of-mass crosses smaller
- Make debug lines thinner for cleaner visualization
