feat: #44 fatura de cartão com data futura fica pendente até confirmação

- Nova tabela pending_bill_imports (migration 016)
- ImportHandler.Confirm: quando is_credit_card=true e payment_date > hoje,
  salva como pending em vez de inserir transações
- Novos endpoints: GET /pending-bills, POST /pending-bills/:id/confirm,
  DELETE /pending-bills/:id
- Dashboard inclui pending_bill_imports no payload
- Frontend: resultado "fatura salva como pendente" no ImportView
- AccountsView exibe widget de faturas pendentes com ações de confirmar/descartar
- dashboard_test: mock de PendingBillRepo + TransactionRepository
