feat: CDI % configurável por conta + fix mocks de teste

- Adiciona campo cdi_percentage (default 100%) na tabela accounts
- Cálculo CDI aplica proporção: balance × (compound-1) × (pct/100)
- Frontend exibe input de % quando yield_type=cdi e badge mostra valor
- Corrige mocks de teste desatualizados (DeleteByMonth, isTax)
- Corrige ConfirmIncome para rejeitar tipo expense (ErrRecurringNotIncome)
