retire frank-medium: tests, planning and observability ground on frank-primary

The frank-medium retirement tail the 2026-09-26 lucebox cutover left
uncommitted: the radiance quadlet tree, its swap/fetch tooling and its
seam test are deleted (archive copies live in dankserver/.AGENTTRASH/
20260926-frank-medium-radiance/ and scripts/.AGENTTRASH/20260926-
frank-medium-radiance/), the planner/allowlist/test-changed mappings
drop the service, and frank-large's chat template moves to scripts/
(its old home was the retired frank-medium dir).

Finished here:
- tests/frank_primary_unit.bats: the lucebox quadlet seam (boot
  persistence, host-network bind, HIP_VISIBLE_DEVICES=0,1, HIP-reserved
  env-name guard, checkout-mounted entrypoint/healthcheck, first-start
  patience, deployer payload/port gates).
- test-changed.sh: explicit .AGENTTRASH/ case — retirement commits move
  files to trash, and the wrapper refused those additions with "no
  focused-test mapping".
- observability: the vllm: namespace left with the radiance runtime.
  Rules keep only llamacpp:* series (prefix-cache reuse, spec-decode,
  queueing, endpoint-down); the dashboard drops the vLLM KV/latency
  panels; prometheus.yml documents that frank-primary (lucebox) has no
  /metrics and therefore no scrape job. llm-fleet.json was left
  corrupted mid-edit (missing opening brace) and is rewritten from HEAD.

Suite: 339 green (was 7 red).
