UX-10 review: the line as logged gets the red-alarm shape, clamp lines at 30 words, plain HA 400

Part 6 checked the quoted reason alone, so title + reason + tails logged
as 4+ sentences. It now also checks the whole line (at most 3 sentences,
none over 30 words); 25 lines failed and are rewritten (one-sentence
wrappers, two-sentence circulation and peak reasons, STALE_READING's
fixed limits on a DEBUG line). The clamp lines for one inverter are
pinned at 30 words with OUTPUT_CLAMP and the numbers kept. Home
Assistant's bare '400: Bad Request' while it loads becomes one plain
line; still WARNING, throttled, a failed write.
