chore(cucumber): add create_pdf_with_black_boxes and convert-pdf-to-image outline; remove duplicate split-pdf-by-sections (#3937)

# Description of Changes

- **What was changed**  
- Introduced `create_pdf_with_black_boxes` helper function in
`environment.py` for generating test PDFs with occluded content.
- Added **Scenario Outline: Convert PDF to image** to
`conversion.feature` to validate PDF→image conversion workflows.
- Removed the duplicate **Scenario Outline: split-pdf-by-sections with
different parameters** from `general.feature`.

- **Why the change was made**  
- To enable testing of blacked-out content scenarios and ensure our
suite covers image conversion.
- To eliminate redundant tests and keep the feature files DRY and
maintainable.
