Make face detection_threshold effective below 0.5
FaceDetectorYN was created with a hardcoded score_threshold of 0.5, so configured face_recognition.detection_threshold values below 0.5 had no effect: lower-confidence faces were discarded inside OpenCV before the config threshold was applied as a post-filter. On cameras with low-resolution detect streams (e.g. 736x416 substreams), real faces routinely score 0.3-0.5 in YuNet, so face recognition never ran on them even though the embedding model handles such crops well. Cap the internal threshold at the configured value instead.
