Add tests for the ToastProvider context, auto-dismiss, and useToast guard

Test the ToastProvider context, auto-dismiss timer, and useToast guard

Description

src/components/ToastProvider.tsx provides app-wide toasts (used by the layout) with a 4s auto-dismiss and a useToast hook that throws outside the provider — none of which is tested. The role="alert" vs role="status" distinction for error/info toasts is a meaningful a11y behaviour worth locking down. This issue adds coverage.

Requirements and context

• Repository scope: Agentpay-Org/Agentpay-frontend only.
• Render a consumer that calls push, assert the message appears, error toasts use role="alert" and info toasts role="status", and the toast disappears after advancing fake timers by 4000 ms.
• Assert useToast() throws the documented error when rendered outside <ToastProvider>.
• Use jest.useFakeTimers() and act for the timer assertions.

Suggested execution

• Fork the repo and create a branch
• git checkout -b test/testing-18-toastprovider
• Implement changes
  • Write comprehensive tests in: create src/components/__tests__/ToastProvider.test.tsx.
  • Add documentation: none beyond test descriptions.
  • Validate the live region container (aria-live="polite") is present.
• Test and commit

Test and commit

• Run npm run lint, npm run typecheck, and npm test.
• Cover edge cases: multiple stacked toasts, default level (info), and the outside-provider throw.
• Include the npm test output and coverage for the component.

Example commit message
