Adds optional live status checking per service (not just per node), requested as a follow-up to issue #196. Backend: - New check_service / check_services: HTTP(S) GET for web services, TCP connect otherwise; UDP and port-less non-web services stay 'unknown'. - New scheduler job 'service_checks', independent interval (default 300s), added/removed live via set_service_checks_enabled. - Settings gain service_check_enabled + service_check_interval (>=30s), persisted to scan_config.json. New WS message type 'service_status'. Frontend: - Live per-service status overlay in canvasStore (not persisted, so it never round-trips through canvas save), fed by the WS message. - DetailPanel + canvas node service rows: offline service turns red (#f85149), otherwise keeps its category colour. - SettingsModal: toggle + interval input (default 300s / 5 min). Off by default — no behaviour change until enabled. ha-relevant: yes
