Feat(service-status): add npm (#516)

npm's status page (status.npmjs.org) runs on Atlassian Statuspage and serves
both /api/v2/summary.json and /api/v2/incidents.json, so it is one provider
row plus its card in ServiceStatus.vue. Its six components are all real
services, so no exclude list is needed.
