feat: integra dados de merchant/checkout no Client 360

Merchants (via br_cb_empresas) agora mostram dados de CambioCheckout:
- fetchMerchantProfile detecta merchant e retorna lifetime checkout stats
- fetchMerchantData retorna KPIs, monthly, top payers e transacoes por periodo
- fetchTopClients inclui checkout volume (merchants sobem no ranking)
- fetchClientSearch inclui merchants nos resultados de busca
- Profile/data endpoints fazem merge automatico dos dados checkout
- UI: badge MERCHANT roxo, 6 hero cards checkout, chart mensal, top 10 payers
