style: apply preferred code style to ScreenCaptureManager classes

Applied user's preferred coding conventions:
- Braces on new line (opening { goes below function/statement)
- Local variables in snake_case for better distinction:
  * display_metrics (instead of displayMetrics)
  * window_manager (instead of windowManager)
  * captured_image (instead of image)

Benefits:
- Improved readability at a glance
- Clear distinction between member variables, parameters, and locals
- Consistent style throughout the new architecture components
