feat(dashscope): 添加 mediaBaseUrl 和万相新模型系列

- 添加 mediaBaseUrl: https://dashscope.aliyuncs.com/api/v1
- 替换旧 wanx-v2 为 5 个最新模型：wan2.7-image-pro、wan2.7-image、wan2.6-t2i、wan2.2-t2i-plus、wan2.2-t2i-flash
- 更新 wanx-video 为 wan2.6-t2v，补充 endpoint 元数据
- 修正尺寸格式为阿里云 API 标准（`*` 分隔符）
- 各模型 extra 中记录 endpoint/asyncHeader/taskQueryEndpoint 供技能直接引用
