// Unit-test the fetch wrapper that every API call flows through. The behaviors
// that matter to the whole app:
//   - it always sends the session cookie (credentials: 'include');
//   - a non-2xx response becomes a thrown ApiError carrying status + a message
//     (server body.message → statusText → generic), never a silent bad value;
//   - an empty body resolves to null (not a JSON parse throw);
//   - JSON bodies get a Content-Type, but a raw FormData upload does NOT (so the
//     browser can set the multipart boundary);
//   - query strings and path params are built/encoded correctly.
// We drive the real req() by mocking global.fetch and inspecting what it received.
