feat(infra): add docker-compose for new Hono services + DB init

- Add mana-user (3062), mana-subscriptions (3063), mana-analytics (3064)
  to docker-compose with health checks and traefik labels
- Replace old NestJS Tier 3 app backends (~300 lines) with comment
  placeholder for Hono compute servers (need shared Dockerfile)
- Create docker/Dockerfile.hono-server — shared Bun Dockerfile for
  all 14 app compute servers (ARG APP for build context)
- Add 5 new databases to setup-databases.sh: mana_auth, mana_credits,
  mana_user, mana_subscriptions, mana_analytics, mana_sync
