feat: implement Trunks with real FreeSWITCH gateway sync

- trunks table (tenant-scoped, RLS): host/proxy/realm, register, username/password_enc (AES-256-GCM), dtmf_mode, ping, transport, and a status/status_updated_at pair meant to be driven by FreeSWITCH events - apps/api/src/trunks: CRUD (POST/GET/GET:id/DELETE), same RBAC/tenant pattern as Extensions, password never exposed in any GET - packages/telephony: buildGatewayXml() generates a Sofia gateway XML file - b2bcall-fs-config now writes sip_profiles/external/<trunk_id>.xml (shared Docker volume with FreeSWITCH -- the vanilla external profile already includes external/*.xml) and runs 'sofia profile external rescan' over ESL; syncs on boot and on demand via Redis pub/sub (b2bcall:trunks:sync), since apps/api runs on the host and fs-config has no port published to reach directly - added FreeSwitchTelephonyProvider.waitUntilConnected() to fix a startup race: the first sync ran before the ESL connection had settled, logging a harmless but noisy error - verified end-to-end with a fake host: create trunk -> gateway file written -> FreeSWITCH shows the real gateway (FAIL_WAIT, expected) -> delete -> file removed (cleanup also correctly swept the stale 'example.com' gateway that had been copied into the volume from the vanilla image) - apps/freeswitch-events/src/trunk-status.ts: written to update Trunk.status from sofia::gateway_state events, using the same normalizeEslEvent path already proven for CHANNEL_* events - KNOWN GAP, documented rather than glossed over: monitored fs-events for ~90s while the gateway visibly transitioned states in FreeSWITCH (FAIL_WAIT/DOWN) and no sofia::gateway_state event was observed arriving. CUSTOM/sofia::* events have not actually been proven working end-to-end in this session -- only CHANNEL_* events have been. Needs verification against a real SIP target before the status auto-update can be trusted in production. See docs/TRUNKS.md and TODO.md. - docs/TRUNKS.md

-## PHASE 09+ — ver `agente.md` seções 41 em diante (Trunks, Dialplan, Call Center,
+## PHASE 09 — Trunks (agente.md secao 41-42)
+- [x] Tabela `trunks` (tenant-scoped, RLS) — host/proxy/realm, register,
+      username/password_enc (AES-256-GCM), dtmf_mode, ping, transport,
+      status/status_updated_at
+- [x] `apps/api/src/trunks`: CRUD (POST/GET/GET:id/DELETE), mesmo padrão de
+      RBAC/tenant de Extensions, senha nunca exposta em nenhum GET
+- [x] `packages/telephony`: `buildGatewayXml()` (XML de gateway Sofia)
+- [x] `b2bcall-fs-config`: gera `sip_profiles/external/<trunk_id>.xml` (volume
+      Docker compartilhado com o FreeSWITCH) e roda `sofia profile external
+      rescan` via ESL — sincroniza no boot e sob demanda via Redis pub/sub
+      (`b2bcall:trunks:sync`, publicado pela API a cada create/delete)
+- [x] Achado: 1º sync no boot corria antes da conexão ESL terminar de se
+      estabelecer (erro cosmético) — corrigido com
+      `FreeSwitchTelephonyProvider.waitUntilConnected()`
+- [x] Testado ponta a ponta com host fake: criar trunk → arquivo gerado →
+      `sofia status gateway` mostra o gateway real (FAIL_WAIT, esperado) →
+      deletar → arquivo removido (limpeza também tirou o `example.com` da
+      vanilla que tinha sido copiado pro volume — comportamento correto)
+- [ ] **Lacuna real, não resolvida**: `Trunk.status` deveria ser atualizado
+      via eventos `sofia::gateway_state` (código escrito em
+      `apps/freeswitch-events/src/trunk-status.ts`, baseado no mesmo
+      `normalizeEslEvent` já testado pra eventos CHANNEL_*), mas o evento
+      **não foi observado chegando** em ~90s de monitoramento mesmo com o
+      gateway mudando de estado de verdade no FreeSWITCH (FAIL_WAIT/DOWN).
+      Os eventos `sofia::*` (CUSTOM) nunca foram provados funcionando nesta
+      sessão — só CHANNEL_* foi verificado de ponta a ponta até agora.
+      Precisa de investigação com um alvo SIP real (outro FreeSWITCH, por
+      exemplo) antes de confiar em atualização automática de status em
+      produção. Ver docs/TRUNKS.md.

+# Trunks (Troncos SIP)
+
+Agente.md seções 41-42. Primeiro recurso que grava configuração real no
+filesystem do FreeSWITCH (gateways Sofia) em vez de só responder via
+`mod_xml_curl`.
+
+## Modelo
+
+`trunks` (tenant-scoped, RLS): `host`, `proxy`, `realm`, `register`,
+`username`/`password_enc` (AES-256-GCM, mesmo padrão de `sip_password_enc`),
+`from_user`/`from_domain`, `register_proxy`/`outbound_proxy`,
+`expire_seconds`, `retry_seconds`, `dtmf_mode`, `ping`/`ping_frequency`,
+`transport`, `max_cps`/`max_channels`, e `status`/`status_updated_at`
+(refletidos pelos eventos do FreeSWITCH, nunca escritos manualmente pela API).
+
+## Mecanismo: por que arquivo + rescan, e não XML Curl "configuration"
+
+Ao contrário de Extensions (resolvido 100% via `mod_xml_curl` na hora do
+lookup), gateways Sofia não têm um binding XML Curl limpo e específico sem
+reativar a seção `configuration` inteira — e isso já causou problemas reais
+na fase XML Curl (chamadas HTTP desnecessárias no boot pra configs de outros
+módulos). Em vez disso, `b2bcall-fs-config`:
+
+1. Gera um arquivo `<trunk_id>.xml` por trunk habilitado em
+   `sip_profiles/external/` (volume Docker compartilhado com o FreeSWITCH —
+   o profile `external` da config vanilla já tem
+   `<X-PRE-PROCESS cmd="include" data="external/*.xml"/>`, então não precisou
+   editar a config do profile).
+2. Roda `sofia profile external rescan` via ESL — relê os gateways sem
+   derrubar chamadas em andamento (diferente de `restart`).
+
+## Gatilho de sincronização
+
+`apps/api` não roda no Docker (ainda está no host) e `fs-config` não expõe
+porta pro host — então a notificação "algo mudou, resincroniza" vai por
+Redis pub/sub (`b2bcall:trunks:sync`), o mesmo mecanismo já usado pra eventos
+normalizados. `apps/api` publica depois de criar/apagar um trunk;
+`fs-config` também roda uma sincronização completa ao subir (cobre trunks
+criados enquanto ele estava fora do ar).
+
+**Achado real**: a primeira sincronização no boot corria antes da conexão
+ESL do `fs-config` terminar de se estabelecer, gerando um erro cosmético
+("FreeSWITCH ESL nao conectado") — a escrita dos arquivos funcionava, só o
+rescan falhava. Corrigido com `FreeSwitchTelephonyProvider.waitUntilConnected()`
+(timeout de 5s) antes de tentar o rescan.
+
+## Status do trunk (secao 42)
+
+`b2bcall-fs-events` já escutava `sofia::gateway_state` desde a fase Event
+Socket (normalizado pra `GATEWAY_UP`/`GATEWAY_DOWN`); nesta fase, ele passou
+a também escrever esse estado de volta em `Trunk.status`. Como o nome do
+gateway no FreeSWITCH é o `Trunk.id` (UUID) e o evento não diz de qual
+tenant é, a busca percorre os tenants ativos (`packages/database`'s
+`withTenantContext`) até achar o trunk dono daquele id — aceitável dado que
+mudança de estado de trunk é rara, não é um evento de alto volume por
+chamada.
+
+Mapeamento de estados brutos do Sofia pro enum interno
+(`apps/freeswitch-events/src/trunk-status.ts`):
+
+```
+UP, REGED       → REGISTERED/UP
+TRYING, REGISTER → TRYING
+FAILED, FAIL_WAIT → FAILED
+DOWN            → DOWN
+NOREG, UNREGED  → UNREGISTERED
+qualquer outro  → UNKNOWN
+```
+
+## Verificado
+
+Criei um trunk de teste apontando pra um host inexistente
+(`sip.trunk-inexistente.invalid`, nunca resolve — RFC 2606) via API:
+
+- `fs-config` sincronizou (`count: 1`), escreveu o arquivo `.xml`, rodou o
+  rescan com sucesso.
+- `sofia status gateway` no FreeSWITCH mostrou o gateway real, estado
+  `FAIL_WAIT` (esperado — host não existe).
+- Confirma o pipeline `API → Postgres → fs-config → arquivo XML → rescan →
+  FreeSWITCH` funcionando ponta a ponta sem precisar de nenhum tronco/
+  credencial real.
+
+## O que falta
+
+- Propagação de `GATEWAY_UP`/`DOWN` → `Trunk.status` não confirmada com
+  evento real disparado por uma mudança de estado ao vivo nesta sessão de
+  testes (o gateway ficou em `FAIL_WAIT` por falha de DNS, que pode não
+  disparar o mesmo ciclo de eventos que uma rejeição SIP normal) — vale
+  reverificar com um destino que responda de verdade (outro FreeSWITCH, por
+  exemplo) antes de confiar nisso em produção.
+- Quota de troncos (`max_trunks`, secao 59) — depende de Plans/Entitlements.
+- `GET /trunks` não mostra `sofia status gateway` ao vivo, só o último
+  status conhecido no banco — suficiente por enquanto, sem WebSocket ainda.
