bujinyuan c3e8600b24 fix: 前后台 Token Redis 存储隔离,修复同账号互相覆盖问题
核心变更:
- Redis key 加入 clientType 前缀:echo:auth:token:{frontend|admin}:{user_id}
- JWT Claims 新增 client_type 字段区分前台/管理端
- 新增 constants/client_type.go 定义 ClientTypeFrontend / ClientTypeAdmin
- 全链路传递 clientType:Controller → Service → TokenStore → Redis
- 中间件从 JWT Claims 提取 clientType 做 Redis 校验
- 登出只删除当前端 Token,不影响另一端

前端变更:
- 管理端 login API 改为调用 POST /api/v1/admin/auth/login(之前错误调用了前台接口)

文档更新:
- 系统设计文档、实施计划、API文档、开发规范、项目进度全部同步
