feat(frontend): Relatórios > Chamadas + Gravações (proxy de áudio autenticado)

Relatórios > Chamadas: lista das últimas 500 chamadas dos últimos 30 dias,
nomes de fila/agente/campanha/disposição resolvidos client-side, busca por
telefone. Só o filtro de telefone nesta primeira versão.

Gravações: lista + player + download. Achado de arquitetura resolvido
antes de codar: <audio src>/<a download> não mandam Authorization Bearer
(só cookie), e a API nunca expõe o storage por URL direta — criado um
proxy autenticado (Route Handler /api/recordings/[id]/audio) que lê o
cookie de sessão, chama a API real com o access token do lado do servidor,
e reencaminha o stream com Content-Disposition: inline (a API manda
attachment). Mesmo princípio de apiFetch: token nunca chega em JS legível.

Testado ponta a ponta contra a API real (estados vazios honestos, proxy
confirmado 401 sem sessão). Smoke test de regressão nas 15 telas
anteriores do tenant + platform, todas 200.
