feat(infra): triggers ERP + reset migrations Prisma para schema correto

Triggers SAR→ERP (scripts/sar-triggers.sql):
- trg_pedido_aprovado: ao aprovar (situa 1→2) em sar.pedidos, replica
  automaticamente em sig.pedidos + sig.peditens e grava erp_id_pedido
- trg_cliente_novo: INSERT em sar.clientes_novos replica em sig.corrent
  com todos os campos obrigatórios; grava id_corrent_erp e flag sincronizado
- Corrige trigger tsvectorupdate do ERP para PG 18 (bpchar→text cast)
- Adiciona coluna erp_id_pedido em sar.pedidos e tabela sar.clientes_novos

Migrations Prisma:
- Remove 5 migrations obsoletas com nomes PascalCase (Order, Client, etc.)
  que não batiam com os @@map snake_case do schema atual
- Cria baseline 20260624000000_init_baseline apontando para estado correto
