-- Accounting integration (D27): Tahesab / Zarrin, chosen in the admin panel.
-- Plan: docs/ACCOUNTING-INTEGRATION-PLAN.md.
--
-- Adds the link table (app row <-> accounting record), the outbox the push
-- jobs run from, the issue list pulls report into, and the cached balance and
-- stock columns read back from the accounting software. Nothing existing
-- changes meaning: goldDebtGrams/fiatDebtRial stay the internal ledger caches.
-- Statements are idempotent so a DB that already has these objects (db push /
-- prior migrate) still records this file without crashing the API boot.
