test(e2e): lift expect timeout to 10s and CI retries to 2 for loaded-runner headroom

A rotating single e2e test failed each CI run (wizard step transition,
list-refetch card provenance, disclosure toggle) while 211 passed — DOM-
settle-gated assertions sampling a mid-transition frame on a starved shared
runner. Raise the global expect timeout 5s→10s (suite-wide settle headroom)
and CI retries 1→2 (absorb the transient without masking a real break, which
fails all attempts). Also scroll the provenance card into view before reading
its attribute, since the mobile timeline can render it off-viewport.
