The run is sized at the batteries' ratings, not the peak limit, so a run too
short to fill a Cheap hours battery is planned again later in the night.
Counting that run alone made B's give grow through the night and A's level
fall after A had bought (round 2: 55 -> 69 -> 41 -> 37 %, A to 56 %).
dayplan._cheap_give_kwh() now also counts the later firm slots before the
expensive hours that a run would still be worth charging in (price + the
spread control asks at most the give run's dearest slot); the Controller
passes the slots and the spread.
test_opt34: back to the original house shapes, fixture and expected values.
B is Off in the nights that test A's level (a Cheap hours B now covers
these hours); B's checks run in new `_b` nights; the 03:00 check runs in a
night from midnight; tail starts A at 60 %; late_fresh reads the kept 6.0.
test_opt36: slot cases, a whole night on one figure (level never moves),
F-1 with B counted (raised level reached and held). test_ux54: the run end
is read from the plan and asserted (02:30); the F1/F2 sweep uses a peak
limit that does not bind and reads a level shown as the target as at it.
