perf(api): чистить старые журналы и облегчить синк и dashboard

- раз в сутки удаляются notification_log и sync_log старше 90 дней и
  vps_health_checks старше 30 дней; синки, зависшие в running дольше
  часа, помечаются ошибкой
- dashboard stats не грузит тарифы, домены и проекты
- запросы характеристик VPS в BILLmanager идут по 4 параллельно
