B-41: 动态主数据——公司、银行账户、别名与审核轨迹

- 公司、公司账号、银行账户、账户类型、户名/账号别名和生效区间
  全部来自数据库,新增公司无需改代码即可检索与使用。
- 公司端提交账户登记,总账端审核为启用/退回/停用;未启用账户
  不参与所有权识别、上传或覆盖计算。
- 账号归一化、脱敏显示与数据库 UNIQUE 约束,并发提交不产生重复
  有效账户;别名匹配有优先级和有效期。
- 所有主数据变更记录前值、后值、操作人、时间和原因。
- 决策记录见 docs/decisions/004-master-data.md。

# 004 动态主数据技术决策
对应 IssueB-41`docs/issues/004-p1-dynamic-master-data.md`)。
## 账户状态机与生效区间
- `bank_accounts.status``pending → active → disabled`,审核退回为
`returned`;退回后同公司重新提交复用同一行并回到 `pending`,不产生
第二条记录。停用这个动作只对 `active` 开放,退回只对 `pending` 开放,
越界操作返回 409。
- 生效区间 `effective_from` / `effective_to`(含当天):公司提交时填写
期望启用日,管理员审核通过时确认;停用时写入 `effective_to`(默认当天)。
- 两个判定函数分开:
- `is_usable`(上传选择、当期操作):仅 `active` 且在生效区间内。
- `is_identifiable`(历史流水所有权识别):`active``disabled` 且在
生效区间内——停用只终止未来参与,不改写历史归属。
## 账号规范化与唯一性
- 账号入库前统一规范化:去空格/短横线、全角数字转半角,只存 6–32 位
数字的规范形式;唯一性由数据库 `UNIQUE(account_number)` 保证,并发
提交必然只有一个成功(有并发测试)。
- 公司端任何响应只含脱敏形式 `****尾四位`;完整账号只在总账管理端
(授权审计视图)返回。审计日志 detail 也只写脱敏账号。
## 别名匹配优先级
- `account_aliases` 支持户名(`name`)与账号(`account`)两类别名,
各自带生效区间和 `priority` 列。
- 匹配优先级确定:精确账号(0)< 账号别名(1000+priority<
户名别名(2000+priority);同层内按 `priority` 再按账户 id 排序。
别名只在自身生效区间且账户 `is_identifiable` 时参与匹配。
## 审计轨迹
- 所有主数据变更写入 `master_data_changes`:实体、动作、前值 JSON、
后值 JSON、原因、操作人、时间。公司创建、账户提交/退回重提/
审核/停用、别名创建全部覆盖,管理员可按实体查询。
## 前端边界
- 公司下拉(往来查询、审核筛选、流水筛选、提醒、期初)和公司表格全部
`/api/admin/companies` 渲染,新增公司无需改代码即可被检索。
- 公司端账户目录、上传账户选择、手工记录资金来源只来自
`/api/company/accounts`,且只有 `usable` 账户进入上传选择。
- 手工记录仍是浏览器 localStorage 演示数据(属 Issue 007/012 范围),
账户登记已完全切换到服务端。

"""Dynamic master data: companies, bank accounts, aliases and audit trail.
Companies, cashier logins and bank accounts live in the database instead of
being hard-coded in the UI. Bank account numbers are stored normalized
(digits only) under a database UNIQUE constraint, so two concurrent
submissions can never produce two usable accounts for the same number.
Company-side registrations are requests: only administrator-approved
(``active``) accounts inside their effective interval may identify ownership,
accept uploads or take part in coverage calculation. Every change is recorded
in ``master_data_changes`` with before/after values, actor, time and reason.
