fix: access correct discoveryInfo property from ObjectStackClient

The ObjectStackAdapter.getDiscovery() was accessing `this.client.discovery`
which doesn't exist on @objectstack/client v2.0.1. The correct private
property name is `discoveryInfo`. This caused getDiscovery() to always
return null, making ConditionalAuthWrapper default auth to enabled,
showing the login page even when auth.enabled=false in server discovery.
