fix(e2e): pick the latest explicit year in the rankings year test

Staging doesn't always carry the full data history, so selecting the
oldest year legitimately returns no rows and fails the promotion gate.
Select the most recent explicit year instead: the default view already
proved it has rows, so an empty table after selecting it can only mean
the year query param was rejected — the regression this test guards.
