…structured (#501)

## Summary

- Make `dpi` an explicit parameter (default 200) on
`convert_pdf_to_image` instead of reading
`inference_config.PDF_RENDER_DPI` internally
- Enables unstructured to import and call this function directly,
eliminating the duplicate `_render_pdf_pages` implementation
- No behavior change — both internal callers already pass `dpi`
explicitly

## Changelog

```
## 1.6.2

### Enhancement
- Make `dpi` an explicit parameter on `convert_pdf_to_image` (default 200) instead of reading from config internally, enabling unstructured to use this as the single source of truth for PDF rendering
```

## Depends on / blocks

- Blocks Unstructured-IO/unstructured#4315 (dedup of PDF rendering)
