Tune simulation parameters, metric system, and preview for Cubes

• Physical model parameters can be changed (are saved into qrs now)
• Dark/light theme can be enforced with environment variable TRIK_STUDIO_THEME
• All kits: trigonometry functions now accesp only radians
• Different fixes and improvements
