feat(crm): catálogos de referencia en BD (SAT/ISO + cliente) — T2026-07-081/082

- Modelo crm.catalog_items (global tenant_id NULL / por tenant) + migración con
  índices únicos parciales y down().
- Seed de 18 catálogos globales (485 opciones): tipo registro/persona, estatus,
  giro, clasificaciones, medio contacto, idioma, régimen, uso CFDI, forma/método
  de pago SAT, moneda/país ISO, estados MX, tipo domicilio, área, cobertura.
- Servicio + endpoints CRUD /v1/crm/catalogs (listar/insertar/editar/borrar),
  con global solo para hub_admin y catálogos del cliente por tenant.
- Columnas nuevas: accounts.commercial_observations, accounts.preferred_contact_other,
  suppliers.classification_other.
