Стабилизация переключения Bridge и Quick Connect

Безопасно восстанавливает управляющее подключение и локальные checkpoint без повторных команд сканеру.

Добавляет PCAP/Bridge guardrails и регрессионные проверки одношагового переподключения.

Известный дефект: после второго подключения интерфейс не присоединяется к новой генерации preview правой камеры. В живой Quick Connect-сессии STOP был принят, но READY не подтвердился до таймаута; автоматический повтор STOP запрещён.
