feat: 新增全局操作密码功能，将线下充值验证从登录密码改为统一操作密码

- 新增 RedisSystemOperationPasswordKey 常量函数（pkg/constants/redis.go）
- 新增 operation_password Service（Set/IsSet/Verify，bcrypt 哈希存 Redis）
- 新增 SuperAdminHandler 及两个接口：
  - POST /api/admin/super-admin/operation-password（设置/重置，仅超级管理员）
  - GET /api/admin/super-admin/operation-password/status（查询是否已设置）
- AgentRecharge.OfflinePay 操作密码验证从"查当前用户登录密码"改为"全局操作密码 Verify"
- Bootstrap/路由/文档生成器同步注册
