/**
 * Zarrin (زرین) — https://zarrin.ir/api-docs/ (the page renders
 * /wp-content/themes/Hirad/data/api.json, 82 entries).
 *
 * Wire format: GET <base>?kind=<api>&token=<token>&<params>, where <base> is
 * the installation's `http://host:8000/ZarrinService/accounting`. The token
 * travels in the query string, so a URL built here must never be logged.
 *
 * Reads verified on a real installation (v228, 870 accounts) on 2026-10-12,
 * ACC-01: negative balance = owes; a «فاکتور موقت» moves the balance at once
 * (unlike Tahesab); listKarSakhte pages by 100 (pageNum); parvande opens with
 * a «مانده از قبل» row that is not a movement; goroohSakhte answers HTTP 400
 * with a good body; infogardeshsakhte answers malformed JSON. Writes verified
 * the same day on test account 953 (addAccount, edithesab, foroushSakhte,
 * hazfRadifSanad); only addFelezsakhteModel is untested. Re-test with
 * scripts/test-accounting-zarrin.ts; the full list is in plan §13.
 *
 * Differences from Tahesab that shape the sync:
 *   * No idempotency key on foroushSakhte. A timed-out document call cannot be
 *     retried blindly — the worker parks it as NEEDS_REVIEW.
 *   * foroushSakhte does not return the row id needed to delete a document;
 *     deleteDocument looks it up from the account's ledger (parvande).
 *   * کارساخته can be created (addFelezsakhteModel) but never edited.
