OPT-36 round 4: count only charge control will make; Solar first drain at the night base

Review F1: a slot after B's run counts only if no slot from the expensive
hours on is cheaper (control plans B's charge left in the cheapest window
ahead), and x 0.95 of B's charge is stored. Three-price night: 1ac7fe9 left
the expensive hours 2.61 kWh short; now 0.
Review F2: a Solar first battery's drain until the expensive hours reads each
hour at no less than the night base (the profile is net of the sun). Read net,
a dark morning drained the battery the plan still counted; A's level fell,
the cheap run moved and was lost before it started (+0.40 EUR per 3 days).
The two real-price replays now cost what 0.20.0 does.
F3: the ux54 sweep's peak limit is 15 kW (the option's top). F4: the rest
comes from the grid (EN/NL). F5: CHANGELOG and DECISIONS wording.
