ha(H2): компонент fglair — manifest, config flow (облако/ручной/импорт), пробная сессия

- custom_components/fglair: manifest (config_flow, local_push, requirements),
  const, trial (start -> ONLINE <=10 c -> GET базовых свойств), FglairClient
  (сессия pyfglair в executor, колбэки в loop, --runtime_data),
  __init__ (setup/unload, рефкаунт глобального лог-пампа)
- config flow: меню cloud/manual/import_json + import-source; discover через
  pyfglair.provision; пробное подключение с диагностикой (cannot_connect,
  no_slots, key_mismatch, timeout, invalid_auth, invalid_import); unique_id=dsn
- strings.json + translations/{en,ru}.json
- тесты HA (pytest-homeassistant-custom-component): меню/шаги/ошибки/импорт/
  облако (discover замокан), setup/unload, занятый порт; trial против
  mock_ac.py (online/key_mismatch/unreachable/no_slots)
- pytest.ini (общий), tests/conftest перенесён на уровень tests/,
  scripts/py-ci.sh: --setup-ha и прогон tests/components
