fix(risk-personnelChange): 修复新增人员变动提交报'未知异常'

根因:
- DB 表 risk_personnel_change 缺少 leave_date 列,但 Do 实体有 leaveDate 字段
  且无 @TableField 注解,MyBatis Plus 按驼峰映射导致 INSERT 报 Unknown column

修复:
- Do.leaveDate 加 @TableField('leave_date') 显式映射
- Service.insertByBo 加 changeCode 自动生成(PC+ts+3位随机),保证 uk_change_code 不冲突
- Service.insertByBo 加 changeDate 前端未传时取当前日期默认值
- Controller.add 移除强制 setAuditStatus(null),让前端/DB DEFAULT 自然生效
