MythEclipse 6d1ede8c2b fix: bulk challenge enable path (compose YAML, base images, async toggle, tooling) 
- fix_dup_volumes.py: 4 canonical templates had TWO volumes: keys inside one
  service (invalid YAML -> 'mapping key volumes already defined'), which broke
  every enable for anti-alchemy/burvesigner/gemas-notes/kode-viewer.
- fjb: ghcr.io base is not anonymously pullable on this host; swapped to the
  official httpd:2.4 (its httpd.conf only uses stock modules). Added
  onlyBuiltDependencies to package.json (pnpm >=10 blocks esbuild's postinstall).
- xl + kode-viewer: node:20-slim-bookworm is not a real tag; use
  node:20-bookworm-slim. gift-voucher: buster -> bookworm.
- prebuild_images.py: build each challenge's shared services-<name> image once
  in parallel (passes a placeholder PASSWORD build-arg, since several Dockerfiles
  run chpasswd and fail on an empty arg).
- set_enabled.py / sync_all_challenges.py: batch registry flip + runtime apply
  that survives panel restarts and reports per-team results.
- Challenge toggle is now async: PATCH returns a job id, the client polls
  /api/challenges/jobs/<id> so a multi-minute build no longer blocks the panel.
  Added _SYNC_LOCK to serialize concurrent compose rewrites.

"""
Gemastik A/D multi-team orchestrator.
Each team gets an isolated stack: its own docker-compose (unique ports +
SSH passwords), its own receiver (unique admin creds + ports), and its own
flags. The orchestrator clones the base services dir, rewrites ports and
passwords, and manages lifecycle via docker compose project per team.
Team N layout:
/opt/gemastik18-final/teams/team<N>/
services/ (docker-compose.yml with team ports + passwords)
receiver/ (.env with team admin creds + container overrides)
receiver/flags/ (per-team flag files)
state.json (team metadata: ports, admin user/pass, ssh creds, created ts)
Port scheme (base offset per team index, index 1-based):
team i: chall ports = 30000 + i*1000 + 0..5 (blogpost,carbeat,cdn,phew,sheesh,warmup)
ssh ports = 30000 + i*1000 + 22..27 (10022-style)
receiver = 30000 + i*1000 + 80 (receiver API, e.g. 31080, 32080)
