ha(H5): обёртка ошибок ESPHome-канала, README/RELEASE/ru-ниты

- ESPHome connect/command/импорт оборачиваются в AcceptanceError; при сбое
  connect канал закрывается (loop закрыт), CLI даёт rc 2 без traceback
- self-test: connect error, command error, отсутствие aioesphomeapi через
  main (rc 2) — всего 15 acceptance-тестов
- RELEASE_HA: repaired-wheel в dist/manylinux + удаление linux-тега перед
  upload; README компонента — корректная ссылка на docs/RELEASE_HA.md
- translations/ru: options data «LAN-ключ»; план §2/§6 синхронизирован
