-- =============================================================================
-- 刷脸照片保留期（最多 1 个月）+ 定期清理任务登记
-- 清理范围：apt_tablet_face_photo 中 COALESCE(uploaded_at, captured_at, create_time)
--           早于 now - retentionDays 的记录：先删文件，再物理删记录。
-- 保留天数由 apt.photo.retention-days 控制（默认 30，上限按业务 1 个月）。
-- 任务：aptPhotoPurgeTask.purge()，建议每天 03:30（避开叫乘高峰）。
-- 幂等：sys_job 按 invoke_target 判重，可重复执行。
