Steps to reproduce

When a Dataset is created and processed using the Knowledge Pipeline feature, documents within that Dataset cannot be downloaded through either the Web Console or the API. This functionality works correctly for standard Datasets created without a pipeline.

1. Create a new Dataset via the Knowledge Pipeline feature.
2. Configure and save the pipeline workflow.
3. Publish the pipeline.
4. Upload a document to the Dataset and wait for the processing/indexing to complete.

✔️ Expected Behavior

• The Download button should be visible and functional in the Dify Web Console for processed documents.
• The document should be successfully downloadable via the official API endpoint: GET /v1/datasets/{dataset_id}/documents/{document_id}/download.

❌ Actual Behavior

• The Download button is completely missing from the Web UI for Datasets utilizing a Knowledge Pipeline (note: it works as expected for standard Datasets).
• Calling the API endpoint GET /v1/datasets/{dataset_id}/documents/{document_id}/download returns a 404 Not Found response.
