/**
 * F1 — {@link MediatedInput} wired to {@link MockInputGateway} through the real
 * {@link DIProvider}. Asserts the mediated-input contract (cadrage §4.2/§6):
 *
 *  - "Envoyer" routes to `InputGateway.submit` with the right args;
 *  - "Interrompre" routes to `InputGateway.interrupt`;
 *  - while busy, "Envoyer" is dimmed/aria-disabled but the enqueue STILL goes
 *    through (forward/fallback — never block the user), and "Interrompre" stays
 *    active.
 *
 * Fully offline: gateways are mocks, no backend.
