fix: 修复后端12个+前端5个高优先级问题

后端:
- devices.js: 修复 newRackId 重复声明、批量移动加事务、ID生成改MAX聚合
- tickets.js: 添加工单状态机校验、req.body白名单过滤
- roles.js: init-roles 添加 authMiddleware
- backup.js: 备份列表只读4KB头部，压缩文件超1MB跳过
- consumables.js: SN查询改用数据库LIKE替代全表扫描
- consumableRecords.js: 出入库加 SELECT FOR UPDATE 行级锁
- inventory.js: not_found 状态判断从 abnormal if 内移到 else if
- idleDevices.js: 删除重复的 batch-restore 路由定义(182行)
- cables.js: 接线冲突检测增加反向端口检查

前端:
- AuthContext.jsx: 初始化时调用 fetchProfile 验证token、Error提取message
- api/index.js: backupAPI.download 返回Promise、checkAdmin改POST
- Login.jsx: checkIsFirstUser 静默处理错误
- DeviceManagement.jsx: 导出 currentPage scope 使用 currentPageDevices
