- Add PDFBox dependency to pom.xml - After storing converted PDF, render all pages via PDFRenderer and upload each as {id}_thumb_p{n}.png - Publish generating_thumbnails WS progress event per page (72-95% range) with "Generated thumbnail N of M" label - Rescale all previous stage percentages to make room: downloading 0-10, preparing 10-15, converting 15-55, verifying 55-63, storing 63-72, thumbnails 72-95, finalizing 95-100
