OPT-11 P4 review: records and text

- DECISIONS: the Cheap hours change and why; the no-sun replay (the gain is
  Leftover solar buying the evening's shortfall; the forecast added 0.14
  EUR); the reconstruction bias stated plainly.
- DOCS: Cheap hours ignores the forecast; a reading from before midnight
  is stale.
- The forecast line: "Solar still to come today: ..." (it is what is
  left, and it stays within the 12-word limit).
