Feat: implementar dashboard de cluster health com QoS e Resource Quotas

Browse Source 
- Adicionar modelos para QoSClassification, ResourceQuota e ClusterHealth
- Implementar classificação automática de QoS (Guaranteed, Burstable, BestEffort)
- Criar análise de Resource Quotas com recomendações automáticas
- Adicionar dashboard principal com visão geral do cluster
- Implementar análise de overcommit com métricas visuais
- Adicionar top resource consumers com ranking
- Criar distribuição de QoS com estatísticas
- Adicionar novos endpoints API para cluster health e QoS
- Melhorar interface com design responsivo e intuitivo
- Alinhar com práticas Red Hat para gerenciamento de recursos
