feat: adiciona informacoes de reinicio e melhora SLA global

- Agente Rust: captura LastBootTime, uptime e contagem de boots
- Backend: extrai campos do extended (bootInfo, discos, RAM, etc) antes de salvar
- Frontend /devices: exibe secao de ultimo reinicio
- SLA global: adiciona campos de modo, threshold de alerta e status de pausa
- Corrige acento em "destinatario" -> "destinatario" em automations
