Add admin summary-PDF download endpoint and button

The weekly summary PDF generated at Thursday close was stored in the
reports bucket with no way to reach it from the UI — admins had to pull
it from S3 manually. Surface it in the admin panel:

- submit_order: GET /api/admin/summary-pdf?week= (admin-gated) returns
  a 5-minute presigned URL from the SUMMARY item's stamped PDF key;
  404 for weeks that haven't closed.
- template.yaml: REPORTS_BUCKET env var + read-only s3:GetObject on
  reports/* for SubmitOrderFunction (needed so the presigned URL is
  signed with sufficient permissions).
- generate_form.py: "Download summary PDF" button in the admin header;
  explains Thursday-close timing on 404.
- Tests: presign happy path, 404 open week, 400 missing week, 401
  unauthenticated.
- README updated.
