catarrh 28a940c9f5 v3.22.1 (review follow-ups): the counter comment, the raw fallback, the RU label
The three nits from the review of the rename/docs commits:

- the PWA comment above TEST_ACTION_KINDS still claimed the final SCP80
  counter is written back - the server persists every consumed counter into
  the preset and the snapshot carries the latest values (display only);
- test-scripts.md's `por` paragraph regained the RM raw fallback the rewrite
  dropped: a remote-management reply that cannot be the compact structure
  (its command count exceeds the command script that was sent, or the data
  is too short for TS 102 226 5.1.2 Table 5.1) is raw too;
- the RU help label reads "Очистка очереди проактивных команд" (the mixed
  Latin "proactive" is gone; the rest of the RU help says "проактивных
  команд").  sw cache simple-v405.

Docs/comment only - tests unchanged and green: 839 frontend + 804 Python.
