fix(system): code-review 15 项修复（预览基数/维度校验/脱敏穿透/并发版本号等）

- 信息员预览基数改用本人销售额（原误用折算毛利润额，金额算错且口径自相矛盾）
- 产品类别入参与维度值加存在性校验（拼错静默回退默认阈值 30% 会算错轨交工资）
- submit 校验顺序前置查库（未注册 param_code 由 500 修正为 400）
- 金额拒绝 NaN/Infinity（比较抛 InvalidOperation、计算抛溢出均穿透为 500）
- version_no 并发冲突翻译为 400（对齐 user/role service 的 IntegrityError 处理）
- 旧值留痕改取条目生效日时点的值（多未来批次下留痕链不再错位）
- 脱敏红线：phone/mobile/id_card 键名整值抹除 + 手机号正则兼容分隔符写法
- 前端：撤回按钮与导出文件名改本地日期（UTC/本地混算）、维度行内精确「改」入口、
  detailOf 补 catch、抽屉分页 size 生效、blob 错误读出真实 message
- e2e 密码移除硬编码 fallback（缺失即报错退出）；按钮文案同步「改」
- 全量回归：后端 406 + 集成 104 + 前端 type-check/build + e2e 7 步 全绿
