// src/services/voiceDiag/checks/callIntercept.js
//
// Detects whether Call Intercept is active. Intercept is a common
// silent cause of "calls just don't come through" — when it's on,
// incoming calls get an announcement instead of ringing the desk,
// and callers hear a generic "the person you're trying to reach is
// not available" prompt with no way to leave a message unless the
// intercept was configured with a rerouting target.
//
// Endpoint: GET/PUT /v1/people/{personId}/features/intercept
//           NOTE the URL segment is `intercept`, not `callIntercept`
//           (the check id keeps the descriptive name for the UI).
// Scope:    spark-admin:people_read (GET) + spark-admin:people_write (PUT).
//
// Response shape (relevant fields):
//   {
//     enabled: true,
//     incoming: {
//       type: 'INTERCEPT_ALL' | 'ALLOW_ALL',
//       voicemailEnabled: true,
//       announcements: {
//         greeting: 'CUSTOM' | 'DEFAULT',
//         newNumber: { enabled: false, destination: '' },
//         zeroTransfer: { enabled: false, destination: '' }
//       }
//     },
//     outgoing: { type: 'INTERCEPT_ALL' | 'ALLOW_ALL', transferEnabled: false, destination: '' }
//   }
//
// Remediation: PUT `{enabled: false}` disables intercept in both
// directions in one call. When the operator wants finer control
// (e.g. only outgoing intercept off) they should do it in Control
// Hub — the bot's role here is to unstick "no calls at all" stores.
