/**
 * Kora Fee Payment Integration Tests
 *
 * Tests the Kora adapter against a running Kora instance.
 * Requires Kora to be running locally (docker compose up) or CI environment.
 *
 * Run locally:
 *   pnpm kora:up && pnpm --filter @sdp/api-integration test
 *
 * Override URL for CI:
 *   KORA_RPC_URL=http://kora:8080 pnpm --filter @sdp/api-integration test
