Add pretty/str/repr to CameraSettings

Introduce a human-readable representation for CameraSettings by adding a pretty() method and overriding __str__ and __repr__. The pretty output formats key fields (name, index, backend, enabled, fps, size, exposure, gain, rotation) and displays a readable crop region (showing 'none' or coordinate range with 'edge' fallbacks). This aids debugging and logging without changing existing validation or behavior.
