### Summary Add support for setting the `status` of `vulnerability_flags` based on AI false-positive detection confidence. New and updated flags will set: * `detected_as_fp` when confidence ≥ 0.6 * `detected_as_not_fp` when confidence < 0.6 Manual dismissals continue to set `status = not_started`. ### Implementation * Update `UpdateAiDetectionService` to derive `status` from `confidence_score`. * Explicitly set `not_started` for manually dismissed flags. * Add a batched background migration to update existing `vulnerability_flags` so their status matches the new logic. ### Result AI detection flags will consistently reflect whether a vulnerability was detected as a false positive.
