test(e2e): widen step-transition and provenance assertion timeouts

The wizard step-advance and the AI-read card marker are gated on async
settles (per-step validation; list invalidate→refetch); on a loaded CI
runner those exceed the default 5s expect timeout, so the assertion samples
a mid-transition frame. Widen just those two assertions to 20s — orthogonal
to test.slow() (which extends the test, not the expect, timeout).
