Seeds one TRACECOIN_BUNDLE package per role (100 Tracecoins / ₹250,
placeholder pricing per your instruction) so the purchase flow
(CreditsPage.tsx -> GET /api/packages, filtered client-side by
role_key) has something to show instead of "No packages available for
your role," and so create_order/verify_payment/invoice generation can
actually be exercised end-to-end. Idempotent (WHERE NOT EXISTS guard)
so it's safe against the custom db-migrate runner re-executing every
file on every deploy. Adjust real pricing later via the existing admin
CRUD (POST/PATCH /api/packages) — no new endpoint needed, it already
works.
Also fixes a unit bug introduced in the invoice wiring last commit:
payments.amount_inr is already paise (copied straight from
pricing_packages.price_inr, which is paise despite the name — PayU
order creation divides it by 100 via paise_to_rupee_string), but the
invoice line item multiplied it by 100 again, making every generated
invoice show a 100x inflated amount.
