feat: 上游 Key 唯一化、分组导入跳过、账号导入平台识别&远端校验&base_url 注入

- 上游 Key 命名改为 {prefix}-{upstream.id}-{safe_group_name}-{group_id}
- 唯一约束 (upstream_id, group_id, managed_prefix) 加 managed_prefix 列
- 上游检测成功时同步 Key 状态，远端已删/分组已删自动清理
- 重复分组导入跳过，目标网站已存在同名分组返回 exists
- 账号导入平台自动识别（auto/manual 模式）
- 全选可导入 Key 按钮 + 目标分组自动匹配
- 导入幂等：已导入过的 Key 校验远端账号，不存在则重建
- 新增同步接口 POST /sync-imported-upstream-keys
- account_exists() 通过拉取账号列表判断，避免 404 误判
- credentials.base_url 注入来源上游地址，避免 401
- 前端导入弹窗自动同步+刷新按钮+并发/优先级设置
- 新增 12 个测试覆盖同步、幂等、远端删除、校验失败路径
