feat v1.11.0: full English translation + en/ru UI localization

- All card UI strings moved to src/i18n.ts (en/ru); language follows the HA
  profile automatically, new 'language: en|ru' card option forces it; GUI
  editor localized and got the language dropdown; generated device names
  localized via BuildCtx.loc.
- English-only codebase: comments, docstrings, test names, backend error
  messages and logs. Russian remains only in the ru dictionary, ru.json,
  iconFor regexes matching Russian device names (+their fixtures) and README.ru.md.
- Docs English-first: README (EN) + README.ru.md, ARCHITECTURE/DEVELOPMENT/
  ROADMAP/CHANGELOG fully translated; translations/en.json had Russian - fixed.
- Removed obsolete RELEASE_NOTES_v1.9.3.md and scripts_publish.sh.
