feat: add login authentication and certificate expiry notifications

- JWT-based login with ADMIN_USER/ADMIN_PASSWORD env config
- Login page with auth guard for Vue frontend
- Feishu bot webhook notification for expiring certificates
- SMTP email notification for expiring certificates
- Daily 8:00 AM cron for expiry checks
- Startup health check notification

+## 证书到期通知
+
+系统支持两种通知方式：
+
+### 飞书机器人
+
+1. 在飞书群中添加 Webhook 机器人
+2. 设置环境变量 `FEISHU_WEBHOOK_URL=https://open.feishu.cn/open-apis/bot/v2/hook/xxxxx`
+
+### 邮件通知
+
+设置 SMTP 相关环境变量：
+```
+SMTP_HOST=smtp.example.com
+SMTP_PORT=587
+SMTP_USER=user@example.com
+SMTP_PASSWORD=your-password
+SMTP_FROM=autossl@example.com
+NOTIFY_TO=admin@example.com,ops@example.com
+```
+
+通知将在每天早上 8:00 自动检查并发送。30 天内到期的证书会触发通知。
