MAI CALL - step 12

Passo 12 completo. Build limpo, AC server-side totalmente verificado.

O que foi implementado:

lib/queue/ — camada de persistência offline:

db.ts — Dexie 4 com tabelas pending e deadLetters
broadcast.ts — BroadcastChannel helper (mai-call-sync) para comunicar entre tabs
sync.ts — loop de sync com retry/backoff: signPhotoUpload → PUT MinIO → create; 409 = sucesso; 4xx = dead-letter; erros de rede = paragem + retry na próxima volta
SyncProvider — React Context que:

Arranca sync ao reconectar (online event + visibilitychange)
Polling de 10s como fallback
Regista Background Sync API quando disponível
Expõe pendingCount / deadLetterCount via useSyncState()
Formulário (/maintenance/new) — refatorado: ao submeter, escreve em IndexedDB e navega imediatamente para /sent sem esperar pelo servidor. O SyncProvider processa a fila em background.

Feedback visual:

SyncChip na home: "Tudo sincronizado" / "N pedidos por enviar" / erro dead-letter
/maintenance/sent: mostra "Em fila" (Clock) ou "Enviado" (CheckCircle2) reactivamente via BroadcastChannel
Workbox (@ducanh2912/next-pwa) — app shell precaching ativo, para que o app carregue mesmo sem rede depois da primeira visita.
