Setup Beam Optimization Study

This script configures the optimization study based on benchmarking results:
- Design variables: beam_half_core_thickness, beam_face_thickness, holes_diameter, hole_count
- Objectives: Minimize stress AND minimize weight (p173 mass)
- Constraint: max_displacement < 10mm
