feat: 系统全面优化 - 设备管理/登录日志导出/性能监控/设置页面
后端: - 新增全局设备管理 API(DeviceHandler.GetAllDevices) - 新增登录日志导出功能(LogHandler.ExportLoginLogs, CSV/XLSX) - 新增设置服务(SettingsService)和设置页面 API - 设备管理支持多条件筛选(状态/信任状态/关键词) - 登录日志支持流式导出防 OOM - 操作日志支持按方法/时间范围搜索 - 主题配置服务(ThemeService) - 增强监控健康检查(Prometheus metrics + SLO) - 移除旧 ratelimit.go(已迁移至 robustness) - 修复 SocialAccount NULL 扫描问题 - 新增 API 契约测试、Handler 测试、Settings 测试 前端: - 新增管理员设备管理页面(DevicesPage) - 新增管理员登录日志导出功能 - 新增系统设置页面(SettingsPage) - 设备管理支持筛选和分页 - 增强 HTTP 响应类型 测试: - 业务逻辑测试 68 个(含并发 CONC_001~003) - 规模测试 16 个(P99 百分位统计) - E2E 测试、集成测试、契约测试 - 性能基准测试、鲁棒性测试 全面测试通过(38 个测试包)
