OPT-36: test_opt34 and test_ux54 scenarios keep a shortfall B does not cover

With Cheap hours B counted, A buys only what B cannot reach. The OPT-34
night scenarios use a 1.6 x larger house profile, and the ux54 tab scenarios
a 4.8 kW evening (ux54_scenarios.make(evening=)), so A still charges; the
hard-coded levels become relations.
