nodeinfo: 2 адреса на сокет (до/после NAT) + типы адресов local/public/nat/nat_eim/nat_strict

- topo_node: сокет рекламирует INTERFACE (до NAT) + NAT (после NAT, EIM);
  strict/direct отдельным адресом не передаются
- topo_node_sqlite: addr_type_classify различает NAT_VERIFIED_*; добавлен
  ADDR_TYPE_NAT (тип неизвестен), fallback больше не даёт DIRECT по IP
- chat_member: бейдж NAT-типа по приоритету (public>nat_eim>nat>nat_strict>local)
  вместо MIN(addr_type)
- GUI (desktop+android): адреса мембера с socket_id и ролью (local/public/nat/nat_eim/nat_strict)
