UX-08 2d: plain log lines, the rest of the status page, and DOCS

Every WARNING and ERROR line is one plain line of at most 25 words, with
no card ids, capitals or semicolons; the reasoning of the ten longest is
on a DEBUG line. The ux08 allowlist is empty and its cap is 0 (43 -> 0).

The status page: the month-peak and peak-guard rows, the stale-reading
row, the top table (Why, Tariff, Arbitrage, Shadow mode, labels), the
Stopped banner and the line under the buttons, which now shows the plain
hint of each event instead of the raw action log. The Supervisor question
at start logs one line with a real reason.

Refusals are counted as shown (labels expanded, long cases driven), seven
were shortened, the card and parse errors lost their internals, a blank
value reads "empty", and the panel no longer files inverters.max_w under
the flat max_w. Option names lose "(JSON)", the NL texts are checked too.

DOCS gets a glossary (control board, isolator, Developer Tools) and card
ids move from headings to a "For installers" line.
