fix(tests): prevent staff redirect loop and fix async test handling

- Add guard to staff redirect to skip redirect if already on /admin route
  This prevents <Navigate to="/admin"> from firing when already at /admin,
  which was causing the admin layout to not render in tests
- Wrap renderApp() in act() to properly flush vi.fn() mock state updates
- Use queryAllByText instead of getByText for nav link checks to handle
  duplicate text elements (nav links vs page headings)
