fix: 修复三个空白页面 + 许可证页面重构

- 修复发现页空白：后端 discover.go nil→[] Match，前端 discover.ts 加 ?? []
- 修复下载客户端页空白：后端 download_clients.go nil→[]model.DownloadClient，前端加 ?? []
- 修复通知渠道页空白：后端 notify_channels.go nil→[]struct{}，前端加 ?? []
- 许可证页面重构：移除生成密钥功能，对接 LicenseServer 绑定/状态模式
- 所有变更通过 Go build + npm run build 零错误验证
