llm: complete the Protoss rename on the wire — served ids frank-archon/dragoon/zealot

The 2026-10-08 rename moved the harness model ids and the homepage cards;
the served aliases on the wire stayed frank-primary/frank-large/
frank-secondary. This closes the gap: the alias each endpoint announces is
now the family name, while the services, units, scripts, env files and
runbooks keep the old names (container identity stays stable).

- scripts/frank-secondary.env ALIAS, scripts/frank-large.env
  HALOGEN_MODEL_ID, scripts/frank-primary.env FRANK_PRIMARY_SERVED_NAME
  (+ the two serve-script defaults/gate messages)
- seams re-pinned: frank_secondary/frank_large/frank_primary unit bats
- fleet harnesses retargeted: bench-probe, deep-probe, calib-push,
  fleet-probes-swift15, autoresearch(+measure), bench-threads-batch-http,
  bench-decode
- shared/homepage/docs.html: api-id annotations and the "switchover will
  rename the ids" footnote removed — the page's names are now the ids;
  opencode/Pi/curl examples send frank-zealot
- dankclaw/hermes/config.yaml.example: frank-large -> frank-dragoon and the
  live 262144 context (Hermes routes by served id; see Hermes.md)

Consumers with live state re-keyed out-of-band in the same window:
OpenWebUI (model row, access_grant, openai.api_configs model_ids) and the
Hermes config.yaml.
