fix: API funcionando com dados reais + dotenv config

- Adiciona dotenv para carregar variáveis de ambiente
- Configura DB_HOST para servidor remoto (176.9.3.158)
- Cria endpoint /api/diagnostic para testes
- Actualiza título: "Plan EAL" → "Dashboard Descomplicar"
- Adiciona tsconfig.json para pasta /api
- Fix: Carrega .env antes de inicializar MySQL pool

Tarefa: #1556
