fix: rewrite HTTP calls to use \$helpers.httpRequest in all code nodes

- Replace require('https') + httpGet with \$helpers.httpRequest() in
  Buscar e Formatar Todos and all 4 tool nodes (more reliable in n8n)
- Switch to parallel requests (Promise.all) in Buscar e Formatar Todos
  for faster execution across 13 clients
- Add ignoreHttpStatusErrors: true so Meta API errors (400 status)
  are returned as JSON and handled gracefully
- Fix Enviar Relatório WhatsApp to use contentType: 'json' with
  explicit body template instead of bodyParameters (avoids encoding issues)
- Add delay: 1500 to WhatsApp messages to avoid rate limiting
