fix(deploy): detect the actually-live blue/green slot, stop nginx-sync clobbering the upstream

- ci-deploy.sh: read_active_port() now probes both slots on /api/health and
  picks the one that really answers; the upstream file only serves as a
  fallback when zero or both slots respond. A stray 'docker compose up' (or a
  clobbered snippet) can no longer derail the next deploy's cutover.
- nginx-sync.sh: cms_upstream_servers.conf is runtime-owned by ci-deploy.sh;
  only seed it when missing, never overwrite what a deploy wrote. This is the
  root cause of tonight's 502: a nginx-sync run reset the snippet (written to
  green:3003 by the last cutover) back to the dead slot A:3002.
- cms_upstream_servers.conf: restore the fresh-host seed default to slot A.

# Op welke poort verwerkt nginx nu verkeer? Onbekend (of geen bestand) betekent
# slot A, zodat de allereerste release op 3002 terechtkomt.
# Welke poort is op dit moment ÉCHT live? Kijk niet naar het upstream-bestand
# (dat kan door een losse `docker compose up` zijn ingehaald en naar een dood
# slot wijzen), maar test welk slot werkelijk antwoordt op /api/health. Alleen
# in een dubbelzinnige situatie (geen óf beide slots gezond) valt het script
# terug op de huidige nginx-pointer; onbekend = slot A (eerste release op 3002).
