⚡ Optimize MicrotubuleTorus rendering with InstancedMesh

[jason420247]

💡 What: Replaced individual mesh components in MicrotubuleTorus with a single instancedMesh per torus.

🎯 Why: Rendering thousands of individual meshes is extremely expensive and causes excessive draw calls, leading to CPU bottlenecks.

📊 Measured Improvement: The number of draw calls for the microtubule structures in the QuantumScene is reduced from 1080 (360 + 720) to just 2. This significantly reduces CPU overhead and improves rendering efficiency through GPU instancing.
