ha(H4): repair key_mismatch, диагностика для ESPHome, reconfigure, переводы

- repairs: issue key_mismatch (ERROR, fixable) при состоянии key_error,
  ConfirmRepairFlow, снятие issue при online/unload/remove
- config flow: async_step_reconfigure (меню, prefill ручной формы,
  unique_id_mismatch, update_reload_and_abort) — путь «перепровижинировать»
- diagnostics: config/esp_home (dsn/lanip_key/key_id/host для secrets.yaml)
  + esp_home_masked и redacted entry_data, runtime-снимок значений
  (raw/display) из кэша ядра
- translations: issues.key_mismatch (title/description/fix_flow) en/ru,
  abort unique_id_mismatch/reconfigure_successful; тест согласованности
  strings↔en↔ru
- FglairClient.events_dropped; mock_ac: параметр key_id в фикстуре
- тесты: diagnostics, repairs issue+fix-flow, reconfigure (успех/чужое
  устройство), translations (45 components)
