SAFETY-125 review: guard row and Home line within UX-08 limits; N=1 maintenance named

- The over-the-limit rows ran over STYLE's 15 words (EN 16/19, NL 16/21)
  and two Dutch Home sentences over 12 words; they were not in the samples,
  so test_messages/test_ux46 never saw them. Now:
  "Peak guard: grid charge limited, at this rate 5 814 W, over 5 413 W" /
  "Piekbewaking: laden beperkt, aan dit tempo 5 814 W, boven 5 413 W",
  "...idle, at this rate ..., over ..." / "...in rust, aan dit tempo ...",
  NL Home "Laadt minder van het net om onder 5,4 kW te blijven." and
  "Zou minder van het net laden om onder 5,4 kW te blijven."
  The rows and the line are added to the samples. The under row is unchanged.
- CHANGELOG known issues and the DECISIONS note: at N=1 the maintenance
  charge is not sized to the room, so SAFETY-99 still applies to it.
- DOCS: the peak guard row's new words.
