fix(renderer): make Scene Lab wireframe toggle visually distinct

[simonhagger]

Summary

• Torus knot geometry was dense enough (220x28) that wireframe rendering looked nearly identical to solid shading; reduced to 128x16 so the toggle is clearly visible
• Material state now applied via \�pplyMaterialState()\ both after scene init and from the signal effect, removing reliance on effect scheduling for post-init state

Validation

• 
  enderer:lint\ +
  enderer:test\ + dev build green
• Live check: wireframe on/off clearly distinct; accent + star color unchanged in behavior
