/**
 * "تکمیل پروفایل" — POST customer/me/complete-profile and its uploads.
 *
 * Ports henza_server Major/CustomerController::complete
 * (app/Http/Controllers/Major/CustomerController.php:73-108).
 *
 * Covers what the owner asked for per page — opening, the empty state, the
 * error state and the main flow — plus the boundaries that matter here:
 *
 *   1. the main flow: three uploads, then complete, then VERIFIED
 *   2. empty/validation: each id missing in turn is a 400/422
 *   3. error: an id that names no file is refused, and nothing is written
 *   4. the customer comes from the TOKEN — no id is accepted from the body
 *   5. no token at all is a 401 on both routes
 *   6. an expert can complete their own profile too (D21: every customer
 *      route works for an expert unchanged)
 *   7. SEC-14: extra body fields are IGNORED, not mass-assigned. The
 *      reference did `$customer->update($request->all())`, which let the app
 *      write gram_level/percent/active onto itself.
 *
 * Every Persian string is a literal here and travels as UTF-8 JSON (D15).
 *
 * Requires the API running WITH OTP_MASTER_CODE set.
 * Usage: node scripts/test-complete-profile.cjs [apiBaseUrl] [masterCode]
