withTestDb sets up an in-memory SQLite handle with migrations applied, swaps the production singleton via _setDbForTest, and restores in a finally block. installFetchStub captures every outbound request and throws if restored twice. requestApp wraps Oak's app.handle so route tests can run without listen(). stubAuthenticate flips the server's authenticator indirection.
