Add source field to DetectedCode and update ScannerView logic for improved barcode handling

- Introduced a `source` field in the `DetectedCode` struct to differentiate between camera and image sources.
- Updated `ScannerView` to enhance the logic for displaying detected codes, including adjustments to the overlay and auto-selection behavior.
- Improved logging for debugging purposes, providing clearer insights into detected codes and their sources.
