feat: 修复仪表盘数据管线 — 补充应用发布种子数据 + 修复limit参数解析 + LDAP认证集成 + User类型完善

后端改进:
- 修复 dashboard/recent-alerts 的 limit 参数解析 (原代码错误地将数字解析为日期)
- 为 dashboard/recent-releases 添加 limit 参数解析支持
- 新增 generateAppReleases 种子数据生成函数 (10条应用发布记录)
- 修复 AlertEvent 的 rule_name/rule_id/severity 数据一致性
- 添加 go-ldap/ldap/v3 依赖并集成 LDAP 认证处理器
- 添加 seed.go 自动种子数据初始化 (admin用户+LDAP配置)
- User model 添加 AuthSource/LDAPConfig 字段

前端改进:
- 修复 User 类型定义以匹配后端 API (real_name/is_admin/auth_source等)
- 修复 Header.tsx 的 real_name 属性引用导致 TypeScript 编译错误
- 统一 API 服务层、暗色主题样式、组件联调优化

验证:
- go build ./... 编译通过
- npm run build 构建通过
- 仪表盘发布历史、告警消息等区域数据正常展示
- 健康检查 /health 正常
