## Title

    Proposed fix: [Docling] ConversionError "Conversion failed because the provided file has no recognizable format or it wasn't in the list of allowed formats."

## Body

    Recommended action: Include the InputFormat in allowed_formats, give DocumentStream a proper filename extension, or use convert(..., raises_on_error=False) and inspect status for batch jobs.
    
    Option: Allow the format / name the stream [evidence: documented_workaround]
    Applies when: Batch ingestion
    Steps:
    1. DocumentConverter(allowed_formats=[InputFormat.PDF, InputFormat.DOCX, InputFormat.HTML])
    2. DocumentStream(name="file.pdf", stream=buf)
    Expected: File converts
