fix(infra): remove n8n and increase health check intervals to fix port exhaustion

Mac Mini had 25k+ TIME_WAIT sockets exhausting the 16k ephemeral port range,
blocking all outgoing TCP connections. Root cause: ~50 health checks at 30s
intervals + n8n automation creating excessive short-lived connections.

- Remove n8n service and volume (no longer needed)
- Increase health check intervals: 30s → 120s (app services), 10s → 30s (infra)
