新增积分系统:打卡/测试达标赚积分,纯累计可配置

- point_rule 规则表 + point_log 流水表(0008 迁移),唯一键防刷:同一事件首次达标才发放,重复静默返回 0
- 打卡分值随任务设置(模板/实例 points 字段,默认 10);测试类 6 种事件按规则表取值,各有默认分(单词 20/数学课 15/语法点 15/周测 50×2/考试通过 100)
- 发放埋点 6 处:打卡、单词检测、数学课、语法知识点、英语/数学周测、考试通过;周测达标联动打卡实例不重复计分
- 孩子端:/kid 总积分徽章,新增 /points 积分页(总积分+流水),测验结果页即时显示「+N 积分」,周测结果页刷新后从流水取回已发积分
- 家长端:功能管理新增「积分管理」Section(规则分值配置+每孩子总积分/最近流水);任务管理内联编辑任务分值
- 修复:drizzle 将 mysql2 重复键错误包进 cause,沿错误链识别 ER_DUP_ENTRY
