Reject unsupported Wan 3.0 size values.

If parameters.size is not in the map and no resolution is set, this code deletes the requested size and selects "1080P". A value such as "640*480" can create an unintended 1080P task and receive the 1080P billing ratio. Reject unmapped sizes before deleting parameters.size.

Preserve parameters.ratio for prompt-only native Wan 3.0 requests.

When a native Wan 3.0 request has no input.media, createVideoTask does not assign requestBody.metadata. convert then applies the default "adaptive" ratio instead of the supplied parameters.ratio. Preserve parameters for every Wan 3.0 native request, and add input.media only when present.

Proposed fix 
-    if (Array.isArray(input.media) && input.media.length) requestBody.metadata = { input: { media: input.media }, parameters: parameters };
+    if (String(req.model).startsWith("wan3.0-video") || (Array.isArray(input.media) && input.media.length)) {
+      requestBody.metadata = { parameters: parameters };
+      if (Array.isArray(input.media) && input.media.length) requestBody.metadata.input = { media: input.media };
+    }
