📋 PR Summary & Link

• **Closes [FEATURE] Configure Cloudinary upload for CDSCO scraper proof archiving #1899 **
• Summary: This PR implements Cloudinary integration within the CDSCO scraper in the ML service to archive visual document proofs. When scanned/image-based PDFs are processed, each page is rendered to a PNG screenshot and uploaded to Cloudinary (under sahidawa/cdsco_proofs), returning a proof_image_url which is stored in the database (drug_alerts table) and validated by the Express API.
  Additionally, this PR fixes a raw merge conflict marker syntax error in apps/ml/routers/asr.py that was committed upstream, and aligns the ASR stream unit tests accordingly.
