Reduce log verbosity and remove auto-load message

Lowered several log statements from INFO to DEBUG in the OpenCV camera backend and camera config preview to reduce noisy logs during normal operation. Removed the deprecated auto-loaded myconfig.json statusBar message in the main window. Also clarified a closeEvent comment and updated a test comment to mark a flakiness note as addressed.
