feat(frontend): Platform > Infraestrutura > FreeSWITCH/SIP Profiles/Nodes

GET /platform/freeswitch/channels|profiles|nodes fazem introspecção ESL real
(show channels/show calls/sofia status/show registrations/status/show gateways),
reaproveitando os métodos do FreeSwitchTelephonyProvider já verificados manualmente
contra o FreeSWITCH real. Mesmo padrão de conexão avulsa do PlatformHealthController
(connect → comando → disconnect).

Nunca deixa a indisponibilidade do ESL virar 500/503 — devolve { ok: false, error }
com 200, mesma filosofia do health check. Necessário: nesta VM apps/api roda fora do
Docker e a porta 8021 é deliberadamente não publicada no host, então as 3 telas
sempre mostram essa explicação aqui (mesmo texto já usado em Infraestrutura >
Saúde), mesmo com o endpoint 100% funcional — confirmado indiretamente pelo
b2bcall-fs-events, que fala ESL de dentro da rede Docker e está com heartbeat ativo.

"Nodes" mostra explicitamente 1 node (container único, sem clustering) em vez de
fingir uma lista.
