refactor(dashboard): reorganizar módulos em subdiretórios e nova arquitetura de widgets

Arquivos de queries, helpers e controllers dispersos na raiz de dashboard/
foram movidos para subdiretórios temáticos (bills/, invoices/, notes/,
notifications/, overview/, payments/, goals-progress/, categories/).
~25 widgets monolíticos obsoletos removidos em favor de nova arquitetura
baseada em widget-registry com components/widgets/. Novos componentes:
category-breakdown-chart/list, goals-progress-item, percentage-change-indicator.
Imports atualizados em fetch-dashboard-data e transaction-filters limpos.
