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.
