Fix docker compose up blocking on frontend healthcheck

- frontend depends_on: service_started (not service_healthy) — docker compose
  up -d now returns once containers start, not after full health chain resolves
- frontend healthcheck: use node HTTP check (wget/curl not in alpine runner)
- start_period: 60s (Next.js can take time on first request)
- on_error: show 60 log lines instead of 30
