/**
 * Rotas de entrada por DID (PHASE 56, docs/INBOUND_ROUTES.md) — achado
 * real: nenhuma chamada de tronco carregava `b2bcall_tenant_id` até aqui,
 * então uma chamada de entrada não tinha como saber de qual tenant é.
 * `didNumber` é @unique GLOBAL de propósito (mesma exceção já aceita em
 * `Tenant.telephonyDomain`) — por isso o conflito de duplicidade só
 * aparece no INSERT (a constraint do banco), nunca por uma pré-checagem
 * cross-tenant: `InboundRoute` tem RLS de verdade (FORCE ROW LEVEL
 * SECURITY), então uma query sem contexto de tenant não veria a linha de
 * outro tenant mesmo se tentasse.
