feat(api): per-license API key management + roadmap sync
API keys (roadmap: 'API key management per license'):
- migration 023_api_keys; ApiKey entity; ApiKeysModule (@Global, exports
ApiKeysService) wired into app.module.
- Service: create (corr_<prefix>_<secret>, returns plaintext once, stores
sha256 hash + prefix), list (no hash), revoke, and validateKey(rawKey) ->
{ license_id } for a future API-key auth guard. Controller license-scoped +
RBAC (apikeys.view/manage).
Roadmap: moved the shipped multi-game items (multi-instance host runtime,
per-game wipe + event scheduling) into a 'Phase 2 — Multi-game runtime' shipped
group; Dune/Conan/Soulmask Formulae stay in-progress.
Backend tsc + frontend build green. Migration applies on a fresh DB (Saturday host).
