feat(#36): receitas recorrentes com confirmação de salário até dia 5

- Migration 009: coluna `type` em recurring_expenses + tabela recurring_late
- API Go: tipo income/expense em CRUD; endpoints POST /confirm e /late
- Dashboard: campo pending_income_recurrings na resposta
- Frontend: RecurringView com seções RECEITAS e DESPESAS separadas
- HomeView: widget de confirmação (dia 1-5) e badge SALÁRIO PENDENTE (pós dia 5)
- Testes unitários: 4 novos casos (income covered, late, confirm, reject expense)
