Add configurable non-transparent OPC UA server redundancy

Browse Source 
Separates ApplicationUri from namespace identity so each instance in a
redundant pair has a unique server URI while sharing the same Galaxy
namespace. Exposes RedundancySupport, ServerUriArray, and dynamic
ServiceLevel through the standard OPC UA server object. ServiceLevel
is computed from role (Primary/Secondary) and runtime health (MXAccess
and DB connectivity). Adds CLI redundancy command, second deployed
service instance, and 31 new tests including paired-server integration.
