Adiciona auto-reload do Chromium via CDP por stream

---

- Adicionado scripts/autoreload.sh: loop com reload via WebSocket CDP raw (net + frames manuais), sem dependências externas; trap de SIGTERM encerra limpo sem aguardar o sleep;
- Adicionado [program:autoreload-{{STREAM_ID}}] em stream.template.conf com autostart=false e autorestart=unexpected;
- Adicionados campos AUTO_RELOAD e AUTO_RELOAD_INTERVAL em reprovision.mjs e supervisor.ts (provisionStream);
- Adicionados campos autoReload e autoReloadInterval em src/types/stream.ts;
- Adicionado autoreload nas listas de startStream e stopStream em supervisor.ts; adicionada função applyAutoReload;
- Adicionado endpoint dedicado POST /api/streams/[id]/autoreload: salva, re-provisiona e aplica sem reiniciar o stream inteiro;
- Adicionado toggle + input de intervalo (minutos) no menu de 3 pontos do card em StreamCard.tsx; toggle pill corrigido com posicionamento left absoluto;
- Atualizado README e CHANGELOG com a nova feature;
