fix: Update netifyd collector for netifyd 5.x stats format

- Collect available stats from status.json (flows_active, flow_count,
  cpu, memory, interface stats) instead of expecting individual flows
- Save current stats to /tmp/netifyd-stats.json
- Maintain history in /tmp/netifyd-stats-history.json (up to 24h)
- Fix architecture detection in plugin-setup script
