/**
 * Test factory helpers.
 *
 * Two flavours:
 *  1. Async DB-inserting factories (makePort, makeClient, makeBerth, makeYacht,
 *     makeCompany, ...) — insert a row via the app's `db` handle and return the
 *     inserted record. Use these from integration tests that need real FK /
 *     unique-index enforcement. They require DATABASE_URL to be reachable.
 *  2. Plain-data helpers (makeAuditMeta, makeCreateClientInput, makeCreate*)
 *     — return in-memory objects suitable for unit tests with mocked `db`.
