Subject: [PATCH] gui: recreate QDBusInterface on service restart

QDBusInterface caches introspection data and can become stale after
the backing service restarts. This caused ListSessions calls to
silently fail, leaving the GUI empty after an olliesrv restart.

Recreate m_iface in the serviceRegistered handler to ensure a fresh
connection to the new service instance.
