Description
Describe the bug
When using partition_pdf on a filepath with analysis=True and a value for pdf_image_dpi, the analysis drawings are at wrong scale.
To Reproduce
file_path = "path_to_my_pdf.pdf"
partition_pdf(filename=file_path, analysis=True, pdf_image_dpi=72, strategy="hi_res")
Expected behavior
Having the drawing at correct scale
Additional context
My understanding is that the problems occures because the function save_analysis_artifiacts called here uses an AnalysisDrawer that calls convert_pdf_to_image without using the pdf_image_dpi given to the partition_pdf function so it uses a 200 dpi value.

Research direction
Start in unstructured/partition/pdf.py at save_analysis_artifiacts and the linked partition_pdf call, then inspect AnalysisDrawer and its convert_pdf_to_image usage. Reproduce the issue with analysis=True, strategy="hi_res", and a non-200 pdf_image_dpi; done means the analysis drawings use the requested DPI and appear at the correct scale.
