Lets the broker's ZarinPal merchant / sandbox / amount-unit be set from Admin → درگاه پرداخت (persisted in payment.settings) instead of env + redeploy, and adds a per-app "test payment" button that mints a real ZarinPal StartPay link straight from the panel — no site wiring needed. - migration 33_payment_settings.sql: singleton payment.settings + a transactions.is_test column. (33, not 32 — 32 is content_render_engine.) - broker read-path precedence: per-client override > DB settings > env. - POST /v1/admin/clients/:id/test-payment + GET/PUT /v1/admin/settings. - admin UI: «تنظیمات زرینپال» tab + «پرداخت آزمایشی» button. Adversarial-review fixes (2 confirmed HIGH): - do NOT pre-seed the settings row — a seeded sandbox=TRUE default would override a production ZARINPAL_SANDBOX=false env and silently route real payments to sandbox.zarinpal.com until an admin untouched the toggle. No row → env governs until an admin saves. - test transactions are tagged is_test and the webhook dispatcher skips them, so an admin smoke-test can never notify (or credit) a real client, regardless of metadata. Broker-authoritative, not consumer-dependent. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
