feat(transactions): edição cooperativa e visibilidade de divisões

Adiciona splitGroupId para vincular as duas shares de um lançamento
dividido (schema + índice + migration 0026). Habilita:

- Edição de par dividido com escolha de escopo (apenas este lado ou
  ambos) via novo SplitPairDialog e updateTransactionSplitPairAction
- Filtro "Somente divididos" (isDivided) na tabela de lançamentos
- Visibilidade de anexos para pessoas com acesso compartilhado via
  payerShares; upload e detach em massa expandem para shares irmãs
- Cópia independente de anexos no fluxo "Importar para Minha Conta"
  (novo fileKey, novo userId, S3 CopyObject) com seção read-only
  "Anexos que serão copiados" no dialog de importação
- Ícone de clipe na tabela de lançamentos da página da pessoa via
  EXISTS em fetchPagadorLancamentos
