Add configurable transport security profiles and bind address

Browse Source 
Adds Security section to appsettings.json with configurable OPC UA
transport profiles (None, Basic256Sha256-Sign, Basic256Sha256-SignAndEncrypt),
certificate policy settings, and a configurable BindAddress for the
OPC UA endpoint. Defaults preserve backward compatibility.
