fix(storage): 修复存储目标编辑不显示配置 & 添加文件列表API

- fix(storage): StorageOut 增加 config 字段并解密返回，编辑时可回填
- fix(storage): Storage ORM 模型添加 config property 支持序列化
- fix(env): 修正 SECRET_KEY 截断、FERNET_KEY 非法占位符问题
- fix(deploy): 后端从 Docker 容器迁移到 systemd 服务，存储目标路径改为宿主机真实路径
- feat(api): 新增 GET /api/storages/{id}/files 文件浏览端点
- feat(frontend): 新增 listFiles API 调用
- docs: 更新 README 反映部署方式变更
