+ * Diferente do InboxView (rota /wa-inbox), NÃO mostra a lista lateral de chats:

+ * Um dropdown permite trocar entre o número do paciente e os do grupo familiar.
+ * Se o paciente ainda não tem conversa, oferece iniciar uma (POST /conversations,
+ * mesmo fluxo do NewConversationModal, que já funciona no satélite via proxy nw).
+ *
+ * Reaproveita a MESMA fiação de hooks do InboxView (stores zustand globais +
+ * socket com guard de conexão), então montar este drawer não duplica a conexão.
