// src/services/voiceDiag/checks/phoneOnline.js
//
// Summarises how many of the store's registered devices are online
// right now, plus a per-device drill-down. Deliberately reuses the
// phone-status snapshot already fetched during buildContext() — this
// check makes ZERO new API calls, which keeps it fast and keeps the
// /voicediag output aligned with /phonestatus for the same store
// (same source, same view of "which phones are up right now").
//
// Signal shape:
//   status: 'error' when at least one phone is offline (a store with
//     a dead phone is a real ticket).
//   status: 'warn'  when the store has no registered devices at all
//     (this is often "we didn't ship / provision yet" but still worth
//     surfacing).
//   status: 'ok'    when every device reports `connected`.
//
// Device shape from collectPhoneStatus:
//   data.phones.data[i] = { mac, name, status, lastSeen, firmware, model, ... }
//   data.dectBasestations[i] = { mac, name, status, lastSeen, firmware, ... }
//
// Statuses observed in the wild: 'connected', 'disconnected',
// 'unknown', 'activating', 'offline'. We treat 'connected' as the
// only truly OK value; everything else counts as offline for the
// purposes of the summary.
