Rename classes to OpcUa* prefix, replace BobinkNode with OpcUaMonitoredNode boilerplate

Rename BobinkAuth → OpcUaAuth, BobinkClient → OpcUaClient (C++ class
names only; QML module URI and singleton name stay as Bobink).
Remove BobinkNode (QQuickItem-based) and add OpcUaMonitoredNode
skeleton using QObject + QQmlParserStatus, following Qt convention
for non-visual QML types.
