OPT-11 P3 review: sale shows no money, honest sell text, tests for four surviving mutants

- A sale block on the plan no longer says "Worth up to" at the import
  price: a sale earns the lower injection price.
- The selling switch help (EN/NL) and DOCS say the grid pays less than
  power costs; DECISIONS records why P3 loses on the replay.
- test_modes_p3 part 11: modes on ignore the site trade switch (R13), a
  battery in maintenance takes no part (R10), a headroom stop latches for
  the period (R8). All three mutants survived before and are red now.
