i18n: fix the LGTM review findings and tidy the branch texts

- i18n scanner: lastError sink, no false sinks on defaults and ternaries
- shared src/i18n/marker.js for modules that only mark strings
- wind field messages move to wind/fields.js; CITY_POIS imports from cityPois.js
- drop review IDs, change history and stale references from comments and docs

+A module the server, tools or other portable code also imports must not load the catalogs: it imports `msg` from `src/i18n/marker.js`, which only marks the text, and the UI translates it with `t()` where it shows it. (Older modules keep a local `const msg = (text) => text`, which works the same.)

 `msg()` exists for two reasons. `npm run i18n` finds messages only as string literals inside `t(…)`, `tn(…)` and `msg(…)`, so `t(FEED_STATE_LABELS[state])` alone tells it nothing. And a `t()` call at module load runs before the page has picked its language, so it would freeze the English.
