Fix TypeScript build errors and improve code quality

- Remove unused variables and imports across components - Fix BabylonJS material property errors (hasAlpha → useAlphaFromDiffuseTexture) - Resolve TypeScript interface extension issues in PhaseViewer - Add null safety checks for potentially undefined properties - Ensure proper array initialization before operations - Clean up unused function declarations 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
