Deploy v6 - Correcao do bug 'tela preta gigante' no fim da page 2873.

Causa raiz confirmada:
- iframe pai tem min-height: 8500px (desktop) / 13000px (mobile) como fallback.
- Quando o postMessage nao roda a tempo (ou o WP calcula body antes do resize),
  o iframe fica travado no min-height e sobra ate 3000px de preto embaixo.
- No mobile o script funciona (recebi 47 mensagens no polling) mas ainda sobra ~150px
  porque body do WP > iframe interno por causa de chrome do The7 (single-share-box,
  ~24px cada, mais o padding do #page).

Fix aplicado:
1. Iframe comeca com height=800px (nao min-height gigante).
2. Script filho manda resize continuo + responde a probe do pai.
3. Script pai:
   a. Escuta o resize e atualiza iframe.style.height (com padding menor: +2px em vez de +10)
   b. Faz polling defensivo: envia probe pro iframe a cada 500ms nos primeiros 6s.
   c. Se apos 4s ainda estiver em <1000px, fallback pra 8500 desktop / 13000 mobile
      (comportamento antigo, mas so como ultima linha de defesa).
4. Fallback CSS removido: min-height so 800px. Se resize falhar completamente,
   apenas fica pequeno em vez de gigante preto.
5. Escondendo tambem .single-share-box e .share-link-description (~24px cada,
   apareceram fora do wrap no diagnostico).
