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

 ## 职责
 
 - 提供 REST 接口（统一前缀 `/api`）
 - 登录鉴权：图形验证码、JWT、登录限流、登出黑名单、登录日志
+- 系统管理（需求 2.5.1）：用户管理、角色管理、岗位角色（#28 可扩展+公式模板绑定）、操作日志（自动审计）、操作与登录日志查询
+- 计提参数体系（需求 #28）：16 项参数目录、按生效日期版本化（回款到账日取值）、变更批次留痕/对比/导出、计算预览
 - 后续承担：基础数据、业务数据、绩效核算、报表统计、T+ 数据同步

+### 操作日志：审计上下文 + 独立提交
+
+写操作统一经 `services/audit_service.py` 的 `audit()` 上下文管理器留痕（用法见 `api/v1/system/users.py`）：
+
+- 调用形态为 DTO：`audit(session, operator=..., record=AuditRecord(module, action, summary, request_data), meta=...)`；落库条目为 `OperationLogEntry`
+- 正常退出记成功；抛异常**先 `session.rollback()` 再**记失败（success=0 + 中文错误原因），随后原异常继续传播
+- 日志**独立 commit**，整体兜底不外抛 —— 方向是「审计可丢，业务不可断」；反向理解：业务失败回滚不会带走失败记录，而那正是审计最需要的
+- **操作人标量在进入上下文时固化**：失败路径先 rollback 会使 ORM 对象过期，之后再读 id/username 会触发额外查询（账号并发被删时 ObjectDeletedError 还会被兜底吞掉）
+- 请求元信息（ip / user-agent / method / path）经路由层的 `RequestMetaDep` 传入 service
+- **commit 之后的任何查询/ORM 读取都要前置**（提到 commit 前或用已固化的局部变量）：业务已提交却因后置查询抛错会被记成「失败」，产生与事实相反的审计
+- 文本列按 `models/operation_log.py` 的长度常量截断；`request_data` 先经**结构化脱敏**（递归按键名整值抹除 password/token 等，不依赖文本模式匹配）再经 `core.logging.scrub` 文本兜底，最后按 **UTF-8 字节边界**截断（encode 带 `errors="replace"` 兜底孤立代理字符）—— 超长/编码异常都会在 MySQL 或 encode 处抛出，被兜底吞掉后表现为「日志莫名消失」
+- **日志列表与详情两段式**：`operation-logs` 列表排除 `request_data`（TEXT 大字段，随列表返回会让翻页负担随表增长），展开详情走 `GET /operation-logs/{id}` 懒加载
+- 模块/操作词表在 `core/constants.py`（`MODULE_*` / `ACTION_*`），前端 `utils/constants.ts` 与其对齐
+
+**角色管理保护规则**（后端是唯一防线，前端按钮禁用只是体验）：admin 角色禁删禁停；有用户绑定的角色禁删（`user_roles` 外键是 CASCADE；删除前走 `SELECT ... FOR UPDATE` 锁行，堵住并发绑定窗口）；`role_code` 创建后不可改；**停用角色不可再分配**（`_resolve_roles` 校验 status，停用只影响新分配、不影响既有授权）。
+
 ## 常见问题
 
 **起服务报 `APP_SECRET_KEY` 相关错误** —— `backend/.env` 未填或不足 32 字符。这是刻意的 fail-fast：空密钥签发 JWT 是安全问题，必须启动即失败。

+需求 2.5.1 要求记录用户的操作行为。与登录行为的分工：登录在 `login_logs`
+单独记录（失败也要留痕且不依赖认证上下文），本模块记录**已认证用户的管理类
+操作**。
+
+设计要点：
+
+- **成功与失败都留痕** —— 失败的操作（如试图删除不存在的用户）同样是审计
+  对象，模型里专门有 `success` / `error_message` 两列承载它
+- **审计失败不影响业务** —— 落库过程整体兜底，失败只记应用日志、绝不外抛
+  （与 `auth_service._record` 同一原则："审计可丢，业务不可断"）
+- **独立提交** —— 日志单独 commit，不与业务同事务。同事务时业务失败回滚会
+  连带丢掉最该留痕的失败记录
+
+用法（上下文管理器）::
+
+    target = user_repository.get_by_id(session, user_id)   # 只读预取，供摘要
+    with audit(session, operator=current_user,

+
+约定：
+
+- 业务代码在上下文内自行 commit（事务边界仍在 service 层）。**commit 之后
+  的任何数据库查询、ORM 属性读取都必须移出上下文**（提到 commit 之前或
+  用已固化的局部变量）—— 业务已提交却因后置查询抛错被记成「失败」，会
+  产生与事实相反的审计记录
+- 上下文内不得吞掉异常后正常退出——吞掉后会被记为成功
+- 摘要需要"目标实体名"时，应在进入上下文**之前**只读预取，
+  这样目标不存在（NotFound 失败）时也能留下可追溯的记录
+- 不支持嵌套（在 audit 内再调用会自行 commit 的服务）——进入侦测到
+  未提交变更会记 warning
