+-- 人员管理(yz_backend_employee) 与 用户管理(yz_system_tenant_user) 老数据对齐
+--
+-- 背景：员工表早期建的是「账号全局唯一」索引 uk_account(account)，多租户后同一账号
+-- 在不同企业只能存在一份员工档案；再叠加历史手工录入的人员（如 hero001 这类旧账号），
+-- 导致「OA 设置 → 人员管理」与「基本设置 → 用户管理」两边数据对不上。
+--
+-- 处理内容：
+--   1. 索引调整为 (tid, account) 唯一  ← 必须最先执行，否则第 3 步会撞全局唯一键
+--   2. 员工 tid 为空/0：按唯一账号补 tid
+--   3. 同一企业内「用户缺员工 + 存在同名无账号老员工」：把老员工账号改成用户账号
+--      （保留员工 ID，排班 / 日报 / 人事档案的历史引用不受影响）
+--   4. 用户仍然没有员工：按用户资料补建员工记录（与「用户管理 → 同步员工」同规则）
+--   5. 复核查询 + 仍需人工确认的清单
+--
+-- 反向缺口（「人员管理有、用户管理没有」）不在这里处理：补账号要先在统一认证建身份
+-- 并生成 argon2id 密码哈希，SQL 做不到，用 Go 工具：
+--   go run scripts/syncemployeeusers/main.go -tid <企业ID> -apply
+--
+-- 特性：可重复执行（幂等），第 2 次执行不会产生任何变更。
+-- 执行前请务必备份：mysqldump -u root -p go-platform > backup_$(date +%F).sql
+-- 执行后请重启 backend 服务：services/employee_sync.go 已改为按 (tid, account) 匹配员工。
