Stand up the payments data foundation: a self-contained `payments` Postgres schema for the in-game currency, wallets, benefits, catalog, orders and the append-only operations ledger, behind a domain package — nothing wired to real money yet. - Migration 00010: the `payments` schema and a NOLOGIN confinement role (ALL on payments.*, nothing on backend); the ledger with a BEFORE UPDATE/DELETE append-only trigger and a partial idempotency index; the materialised balances/benefits; the catalog (atoms seeded) + products + per-method prices; the typed single-row config; orders and payment_events. There is no cross-schema foreign key — account_id is a plain uuid kept consistent in code, which keeps the domain extractable. Expand-contract and reversible. - Money is a bigint in the currency's minor units carried by a `Money` value type (exact, math/big): no float ever touches an amount, and a whole-unit currency cannot hold a fraction. - Extend jetgen to generate the payments schema; construct the service in the composition root behind a narrow interface with a boot reachability check. - Tests: integration (role confinement via SET ROLE, the append-only trigger, CHECK constraints, the idempotency index, and a forward+backward migration), Money unit tests, and an import-boundary test keeping the payments jet code private to the domain. - Docs: PLAN.md, docs/PAYMENTS.md (+ _ru mirror) updated to the built model.
