feat(app): страница здоровья вместо разрозненных /sync и data quality

/sync и блок data quality на дашборде сведены в один /health с двумя
вкладками (Источники, Качество данных); дашборд ссылается на неё вместо
собственного bottom sheet. Список находок вынесен в общий виджет
DataQualityList, чтобы не дублировать рендер.
