This commit adds a quality filtering feature to the Identify Panel, allowing users to filter faces based on a quality score (0-100%). The `_get_unidentified_faces()` method has been updated to accept a `min_quality_score` parameter, and the SQL query now includes a WHERE clause for quality filtering. All relevant call sites have been modified to utilize this new feature, improving the user experience during face identification. The unique checkbox default state has also been confirmed to be unchecked, ensuring consistency in the UI behavior.
