Fix preview to show actual capture aspect ratio

Browse Source 
Changes:
1. Preview layer now uses .resizeAspect instead of .resizeAspectFill
   - Shows exactly what will be in the captured photo
   - No cropping - what you see is what you get
   - Ring light naturally fills any letterbox areas

2. Session preset changed from .high to .photo
   - Optimized for photo capture
   - Consistent 4:3 aspect ratio
   - Better quality for selfies

This ensures the preview accurately represents the final photo,
eliminating surprise cropping in captured images.
