Consolidate LDAP roles into OPC UA session roles with granular write permissions

Browse Source 
Map LDAP groups to custom OPC UA role NodeIds on RoleBasedIdentity.GrantedRoleIds
during authentication, replacing the username-to-role side cache. Split ReadWrite
into WriteOperate/WriteTune/WriteConfigure so write access is gated per Galaxy
security classification. AnonymousCanWrite now behaves consistently regardless
of LDAP state.
