refactor: faxina arquitetural — código morto, identificadores em inglês e estrutura padronizada

Refatoração estrutural sem mudanças funcionais. Saldo líquido: −428 linhas.

Removido:
- 14 funções/constantes mortas verificadas via grep no repo todo: validateCategoriaOwnership,
  getInstallmentAnticipationsAction, getAnticipationDetailsAction, formatDecimalForDb,
  currencyFormatterNoCents, optionalDecimalSchema, formatMonthLabel,
  getGoalProgressStatusColorClass, MONTH_PERIOD_PARAM, calculateRemainingInstallments,
  e 5 funções fetch* não usadas em inbox/queries.ts.
- 1 tipo morto (ImportRow) + 2 órfãos consequentes (InstallmentAnticipationWithRelations,
  GoalProgressStatus convertido em interno).
- ~30 export keywords desnecessários (símbolos usados apenas no próprio arquivo).
- Re-exports mortos em barrels: EstablishmentLogoPicker, CategoryReportSkeleton,
  WidgetSkeleton, toNameKey.
- Arquivo features/reports/types.ts (barrel inteiro era órfão).

Padronizado (PT-BR→EN em identificadores expostos):
- 4 constantes globais (LANCAMENTOS_* → TRANSACTIONS_*).
- 12 tipos/interfaces (Lancamento*/Pagador*/Estabelecimento* → equivalentes EN).
- 13 funções/components exportados (fetchPagador*, EstabelecimentoInput, PagadorInfoCard, etc.).
- 5 props cross-file (preLancamentosCount → inboxPendingCount, pagadorAvatarUrl → payerAvatarUrl, etc.).
- Mantidas em PT-BR conforme exceção do CLAUDE.md: variáveis locais (pagador, categoria,
  lancamento), accessor key pagadorName (persistida em preferências), strings de UI.

Reorganizado:
- transactions/: 14 helpers soltos na raiz movidos para lib/; barrel actions.ts reduzido
  de 76 linhas de wrappers para 14 linhas de re-exports puros; anticipation-actions.ts
  movido para actions/anticipation.ts.
- dashboard/: 8 helpers soltos consolidados em dashboard/lib/.
- reports/: 5 query files na raiz consolidados em reports/lib/.
- payers/: detail-actions.ts (21KB) e detail-queries.ts movidos para payers/lib/.
- shared/components/: 9 dos 16 componentes soltos agrupados em brand/, widgets/, feedback/.
- shared/lib/fetch-json.ts movido para shared/utils/fetch-json.ts.

Validação: pnpm exec tsc --noEmit (0 erros), biome check (0 issues), knip (sem unused).
