email(healthcare): add not-affiliated disclaimer to all HC campaigns + scrub mechanics

- Add the 'Performance West is an independent compliance firm, not affiliated
  with CMS or Medicare' footer disclaimer to the 4 remaining HC emails
  (reactivation, NPPES, OIG/SAM, bundle), matching the revalidation email.
  OIG email also names the OIG and SAM.gov it references.
- Scrub client-facing mechanics: drop the CMS-855 form number from the
  reactivation CTA and the PECOS system name from the revalidation CTA; clean
  the same out of source comments.
