test: raise Testing Library async timeout to 5 s

The frontend image build runs ~240 spec files on a loaded runner; a first
render in apiary-colonies-card.spec missed the default 1 s findByRole
window in CI run 711 while it passes locally. 5 s stays well below the
15 s test timeout, so real hangs still show.
