feat(alerts): алерты всей команде — детекторы, дедупликация, список (#15)

- детекторы по состоянию после каждого раунда снапшотов: краш, OOM,
  цикл рестартов, unhealthy, перегрузка ≥ 1 мин, мало места, Docker
  недоступен; пороги в config/alerts.yaml
- AlertService: ключ kind+service, повтор в 10 мин — счётчик в исходном
  сообщении, «✅ восстановлено» ответом; разовые события (🛡) со счётчиком
- рассылка всем активным (🛡 — только админам), темп ~25/с, RetryAfter,
  заблокировавший бота пропускается; alert_deliveries для правок и ответов
- «🚨 Алерты»: активные + 7 дней по 10, карточка; кнопки «📜 Логи»,
  «🩺 Статус» под алертом открывают новое сообщение, а не затирают алерт
- 🛡 атаки через агента идут через общий сервис алертов
- убраны заглушки «Раздел в разработке» — у всех разделов свои роутеры
