feat(resellers): UI de CNPJ/sócios/endereço/contatos, na ordem certa

Mesma UI construída pro Cadastro de Cliente, aplicada a Revenda, já
direto na ordem pedida (Dados -> Sócios -> Endereço -> Contatos), sem
precisar de uma segunda leva de reordenação. Criar uma revenda agora
redireciona pra edição dela (não pra lista) já que CNPJ-lookup/Sócios
só fazem sentido com um id existente. PartnersSection generalizada
para reuso entre Cliente e Revenda.

Corrige um bug real encontrado na verificação ao vivo: o rótulo do
botão de busca estava amarrado ao que estava sendo digitado, não ao
que já foi salvo — digitar um CNPJ válido trocava pra "Buscar
novamente" antes de qualquer busca real acontecer.

Suíte: 106/106 (inalterada). pnpm turbo run typecheck build: 28/28.
Testado ao vivo com CNPJ real (Petrobras).
