The Dockerfile copies form PDFs explicitly by name; the SC COC template was
missing, so fill_sc_coc() would FileNotFoundError in the container. Added it.
- cms855_pdf_filler.py: fills official CMS-855I/B/O/A AcroForms from intake
(name, NPI, DOB, cert-page printed name) and records the signature anchor at
the form's official /Sig box so the e-sign stamper lands on the cert line.
- npi_provider handlers (revalidation/reactivation/enrollment) now generate the
paper CMS-855, upload it to MinIO, request_esign with anchors, and email the
signing link. Human completes/verifies + USPS Priority Mails to the MAC.
- scripts/Dockerfile: copy the official CMS-855I/B/O/A forms into the image.
