Sync cezen-portal/ from live working copy (V1.0 GA polish + search-icon ordering fix)

Brings the ISO-packaged portal copy current with the live cezen-portal/
working directory, which had drifted across the entire V1.0 GA polish
initiative (Phases 1-10) plus this session's topnav icon-order bugfix.

- 52 existing files updated, 2 new pages added (about.html, health.html)
- cgit/cezen-portal/ is now byte-identical to cezen-portal/
- Backend files (rag_ingest.py, cezen_license.py) already in sync;
  main.py intentionally left as-is (cgit is ahead there with
  workstation-category commercial-fit logic not yet backported to the
  live working copy)

Next: rebuild the ISO (bash autoinstall/build-iso.sh) to bake this in.
