feat(deploy): 正式環境部署設定

- frontend/api.js: API URL 自動判斷 (localhost=dev, 其他=相對路徑 /api/v1)
- main.py: 加入 StaticFiles 掛載 admin-portal，CORS 開放
- schedule_tenant: Traefik 路由範本更新
  - 管理租戶加入 /api 路由 (priority 200)
  - /admin 加入 StripPrefix middleware
  - admin 服務改指向 vmis-backend:10281
- docker/vmis: 新增 Dockerfile + docker-compose.yml
