Pie menu: show ortho_scale instead of focal length for Orthographic cameras

[Weisl]

Problem

The pie menu's Lens section always shows Focal Length and Field of View (angle), which are perspective-only properties. When the active camera is set to Orthographic, these controls are misleading — Blender uses ortho_scale for orthographic cameras, not a focal length.

Solution

Conditionally swap the Lens block based on cam.type:

• Perspective / Panoramic → show lens (focal length) + focal length preset dropdown + angle (FOV) — no change
• Orthographic → show ortho_scale instead

Files Changed

• pie_menu.py — draw_camera_settings(): added cam.type == 'ORTHOGRAPHIC' branch
