fix: corrigir tipos de servidor AMD (CPX→CX), autoscaler, stdin e cleanup

- Corrigir tipos Hetzner: CPX não existe, usar CX (Intel shared vCPU)
  - CX23 (2 vCPU, 4GB) equivalente ao CAX11
  - CX33 (4 vCPU, 8GB) equivalente ao CAX21
  - CX43 (8 vCPU, 16GB) equivalente ao CAX31
- Corrigir location no autoscaler para amd64 (nbg1→fsn1)
- Remover gitlab-pool do autoscaler (substituído pelo Gitea)
- Aumentar worker-pool max para 30
- Corrigir Floating IP e Load Balancer hardcoded em nbg1
- Corrigir stdin em read interativo: usar < /dev/tty e read -p
- Corrigir cleanup de namespace: lidar com Terminating e finalizers
- Corrigir CNPG: nome do deployment, secret e endpointURL duplo
- Aulas afetadas: 08, 09, 10, 11, 12, 14, 17
