ha(H3): превью шаблона с конверсиями; climate и сущности

- config flow: шаг preview (шаблон A/B/F, диапазон/шаг уставки, линейные
  коэффициенты num/den/offset, текст-превью по данным trial: hvac/fan/
  swing/capabilities/текущая температура)
- coordinator: push-driven DataUpdateCoordinator (снимок кэша, доступность
  online/recovering, первичный GET-батч, один batch_commit на действие)
- overrides.py: ConversionSet (ручные линейные конверсии и диапазон поверх
  таблиц ядра, применяются в HA)
- entity.py: DeviceInfo/unique_id/доступность, capabilities-фильтры
- climate: hvac/fan/swing/vertical+horizontal swing/preset ECO-BOOST,
  уставка 16-30 °C (шаг по шаблону), current_temperature
- sensor: room_temperature, error_code, connection_state (диагностика)
- binary_sensor: connectivity + флаги op_status (PROTOCOL §8.4)
- switch: 8 флагов-свойств; select: положения заслонок 0..N-1
- тесты: превью/конверсии/ошибки диапазона, сущности против mock_ac
  (снимок, команды, capabilities-фильтр, ручная конверсия), ConversionSet
- mock_ac: --set NAME=VALUE (0b/0x) для сценариев
- план: demand_control отложен (семантика не зафиксирована)
