OPT-34 fix (rig F-1): a replaced evening forecast does not come back

After a fresh today reading in the night (02:00 on the rig) went stale
(05:00), Hold.stand_in(as_today=True) served the 17:05 "tomorrow" figure
again until 06:00: the plan went back to 95 %, the latch took it, and
Leftover solar charged back up. read_sum() now skips that stand-in once
every today sensor has given a fresh reading for the day
(Hold.replaced()); the stale newer reading follows the OPT-27 rules.

 - The night grid charge no longer raises "Battery stopped limiting the peak" when the 15-minute period stays on the aim. A steadily rising load now alarms a little later, and with a peak margin of 0 a period can end up to 10 W over the limit without this alarm ([[SAFETY-126]]).
-- A night grid charge for *Leftover solar* no longer stops at 03:00 when the solar forecast sensors went quiet in the evening. The evening's figure is used until 06:00, and a charge that has started goes on to its level ([[OPT-34]]).

 **A patch bump: two fixes, one for charging from the grid under the peak limit and one for the night charge of Leftover solar, and no option changes.**
 No option was added, removed or renamed, and no default changed (86 options).
