已完成管理后台第三批 ASP.NET Core 10 迁移：批量报名号申领与审批。

原生接口：
GET /api/admin/candidate-account-batches
POST /api/admin/candidate-account-batches
PATCH /api/admin/candidate-account-batches/{batchId}
实现包含：
校级管理员按班级提交名额
可配置多级审批流与待办负载分配
当前处理人及管理员层级校验
审批通过、退回和重复审批保护
终审时原子生成考生账号、报名号、初始密码和待补录资料
生成账号兼容现有 PBKDF2 登录及首次强制改密
